Ideal Upgrade for TLC27x Family
description
The TLV27x takes the minimum operating supply voltage down to 2.7 V over the extended industrial
temperature range while adding the rail-to-rail output swing feature. This makes it an ideal alternative to the
TLC27x family for applications where rail-to-rail output swings are essential. The TLV27x also provides 3-MHz
bandwidth from only 550 μA.
Like the TLC27x, the TLV27x is fully specified for 5-V and ±5-V supplies. The maximum recommended supply
voltage is 16 V, which allows the devices to be operated from a variety of rechargeable cells (±8 V supplies down
to ±1.35 V).
The CMOS inputs enable use in high-impedance sensor interfaces, with the lower voltage operation making
an attractive alternative for the TLC27x in battery-powered applications.
All members are available in PDIP and SOIC with the singles in the small SOT-23 package, duals in the MSOP,
and quads in the TSSOP package.
The 2.7-V operation makes it compatible with Li-Ion powered systems and the operating supply voltage range
of many micropower microcontrollers available today including TI’s MSP430.

description
The TLC27L2 and TLC27L7 dual operational
amplifiers combine a wide range of input offset
voltage grades with low offset voltage drift, high
input impedance, extremely low power, and high
gain.
These devices use Texas Instruments silicon-gate LinCMOS technology, which provides offset voltage
stability far exceeding the stability available with conventional metal-gate processes.
The extremely high input impedance, low bias currents, and low power consumption make these cost-effective
devices ideal for high gain, low frequency, low power applications. Four offset voltage grades are available
(C-suffix and I-suffix types), ranging from the low-cost TLC27L2 (10 mV) to the high-precision TLC27L7
(500 μV). These advantages, in combination with good common-mode rejection and supply voltage rejection,
make these devices a good choice for new state-of-the-art designs as well as for upgrading existing designs.
In general, many features associated with bipolar technology are available in LinCMOS operational amplifiers,
without the power penalties of bipolar technology. General applications such as transducer interfacing, analog
calculations, amplifier blocks, active filters, and signal buffering are easily designed with the TLC27L2 and
TLC27L7. The devices also exhibit low voltage single-supply operation and ultra-low power consumption,
making them ideally suited for remote and inaccessible battery-powered applications. The common-mode input
voltage range includes the negative rail.
A wide range of packaging options is available, including small-outline and chip-carrier versions for high-density
system applications.
The device inputs and outputs are designed to withstand −100-mA surge currents without sustaining latch-up.
The TLC27L2 and TLC27L7 incorporate internal ESD-protection circuits that prevent functional failures at
voltages up to 2000 V as tested under MIL-STD-883C, Method 3015.2; however, care should be exercised in
handling these devices as exposure to ESD may result in the degradation of the device parametric performance.
The C-Suffix devices are characterized for operation from 0°C to 70°C. The I-suffix devices are characterized
for operation from −40°C to 85°C. The M-suffix devices are characterized for operation over the full military
temperature range of −55°C to 125°C.

TAS1020B
USB Streaming Controller
1.2 Description
The TAS1020B integrated circuit (IC) is a universal serial bus (USB) peripheral interface device designed
specifically for applications that require isochronous data streaming. Applications include digital speakers,
which require the streaming of digital audio data between the host PC and the speaker system via the
USB connection. The TAS1020B device is fully compatible with the USB Specification Version 1.1 and the
USB Audio Class 1.0 Specification.
The TAS1020B uses a standard 8052 microcontroller unit (MCU) core with on-chip memory. The MCU
memory includes 8K bytes of program memory ROM that contains a boot loader program. At initialization,
the boot loader program downloads the application program code to a 6,016-byte RAM from either the
host PC or a nonvolatile memory on the printed-circuit board (PCB). The MCU handles all USB control,
interrupt and bulk endpoint transactions. DMA channels are provided to handle isochronous endpoint
transactions.
The USB interface includes an integrated transceiver that supports 12 Mb/s (full speed) data transfers. In
addition to the USB control endpoint, support is provided for up to seven IN endpoints and seven OUT
endpoints. The USB endpoints are fully configurable by the MCU application code using a set of endpoint
configuration blocks that reside in on-chip RAM. All USB data transfer types are supported.
The TAS1020B device also includes a codec port interface (C-Port) that can be configured to support
several industry standard serial interface protocols. These protocols include the audio codec (AC) '97
Revision 1.X, the AC '97 Revision 2.X and several inter-IC sound (I2S) modes.
A direct memory access (DMA) controller with two channels is provided for streaming the USB
isochronous data packets to/from the codec port interface. Each DMA channel can support one USB
isochronous endpoint.
An on-chip phase lock loop (PLL) and adaptive clock generator (ACG) provide support for the USB
synchronization modes, which include asynchronous, synchronous and adaptive.
Other on-chip MCU peripherals include an inter-IC control (I2C) serial interface, and two 8-bit
general-purpose input/output (GPIO) ports.
The TAS1020B device is implemented in a 3.3-V 0.25 μm CMOS technology.

OCTAL BUS TRANSCEIVER AND 3.3-V TO 5-V SHIFTER
WITH 3-STATE OUTPUTS
FEATURES
Bidirectional Voltage Translator
· 5.5 V on A Port and 2.7 V to 3.6 V on B Port
· Control Inputs VIH/VIL Levels Are Referenced
to VCCA Voltage
· Latch-Up Performance Exceeds 250 mA Per
JESD 17
· ESD Protection Exceeds JESD 22
– 2000-V Human-Body Model (A114-A)
– 200-V Machine Model (A115-A)
– 1000-V Charged-Device Model (C101)
DESCRIPTION/ORDERING INFORMATION
This 8-bit (octal) noninverting bus transceiver
contains two separate supply rails; B port has VCCB,
which is set at 3.3 V, and A port has VCCA, which is
set at 5 V. This allows for translation from a 3.3-V to
a 5-V environment, and vice versa.
<br/>
The SN74LVC4245A is designed for asynchronous communication between data buses. The device transmits
data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the
direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so the buses are
effectively isolated. The control circuitry (DIR, OE) is powered by VCCA.
The SN74LVC4245A pinout allows the designer to switch to a normal all-3.3-V or all-5-V 20-pin '245 device
without board re-layout. The designer uses the data paths for pins 2–11 and 14–23 of the SN74LVC4245A to
align with the conventional '245 pinout.

PARALLEL-LOAD 8-BIT SHIFT REGISTERS
Complementary Outputs
Direct Overriding Load (Data) Inputs
Gated Clock Inputs
Parallel-to-Serial Data Conversion
description
The ’165 and ’LS165A are 8-bit serial shift
registers that shift the data in the direction of QA
toward QH when clocked. Parallel-in access to
each stage is made available by eight individual,
direct data inputs that are enabled by a low level
at the shift/load (SH/LD) input. These registers
also feature gated clock (CLK) inputs and
complementary outputs from the eighth bit. All
inputs are diode-clamped to minimize
transmission-line effects, thereby simplifying
system design.
Clocking is accomplished through a two-input
positive-NOR gate, permitting one input to be
used as a clock-inhibit function. Holding either of
the clock inputs high inhibits clocking, and holding
either clock input low with SH/LD high enables the
other clock input. Clock inhibit (CLK INH) should
be changed to the high level only while CLK is
high. Parallel loading is inhibited as long as SH/LD
is high. Data at the parallel inputs are loaded
directly into the register while SH/LD is low,
independently of the levels of CLK, CLK INH, or
serial (SER) inputs.

sn74hc373
Wide Operating Voltage Range of 2 V to 6 V
High-Current 3-State True Outputs Can
Drive Up To 15 LSTTL Loads
Low Power Consumption, 80-μA Max ICC
Typical tpd = 13 ns
±6-mA Output Drive at 5 V
Low Input Current of 1 μA Max
Eight High-Current Latches in a Single
Package
Full Parallel Access for Loading
description/ordering information
These 8-bit latches feature 3-state outputs designed specifically for driving highly capacitive or relatively
low-impedance loads. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional
bus drivers, and working registers.
The eight latches of the ’HC373 devices are transparent D-type latches. While the latch-enable (LE) input is
high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels that
were set up at the D inputs.
An output-enable (OE) input places the eight outputs in either a normal logic state (high or low logic levels) or
the high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines
significantly. The high-impedance state and increased drive provide the capability to drive bus lines without
interface or pullup components.
OE does not affect the internal operations of the latches. Old data can be retained or new data can be entered
while the outputs are off.

description/ordering information
These circuits are positive-edge-triggered D-type flip-flops with a direct clear (CLR) input.
Information at the data (D) inputs meeting the setup time requirements is transferred to the Q outputs on the
positive-going edge of the clock (CLK) pulse. Clock triggering occurs at a particular voltage level and is not related
directly to the transition time of the positive-going pulse. When CLK is at either the high or low level, the D input has
no effect at the output.

8-BIT PARALLEL-OUT SERIAL SHIFT REGISTERS
Wide Operating Voltage Range of 2 V to 6 V
Outputs Can Drive Up To 10 LSTTL Loads
Low Power Consumption, 80-μA Max ICC
Typical tpd = 20 ns
±4-mA Output Drive at 5 V
Low Input Current of 1 μA Max
AND-Gated (Enable/Disable) Serial Inputs
Fully Buffered Clock and Serial Inputs
Direct Clear
description/ordering information
These 8-bit shift registers feature AND-gated
serial inputs and an asynchronous clear (CLR)
input. The gated serial (A and B) inputs permit
complete control over incoming data; a low at
either input inhibits entry of the new data and
resets the first flip-flop to the low level at the next
clock (CLK) pulse. A high-level input enables the
other input, which then determines the state of the
first flip-flop. Data at the serial inputs can be
changed while CLK is high or low, provided the
minimum setup time requirements are met.
Clocking occurs on the low-to-high-level transition
of CLK.

Incorporate Two Enable Inputs to Simplify
Cascading and/or Data Reception
description/ordering information
The ’HC139 devices are designed for
high-performance memory-decoding or
data-routing applications requiring very short
propagation delay times. In high-performance
memory systems, these decoders can minimize
the effects of system decoding. When employed
with high-speed memories utilizing a fast enable
circuit, the delay time of these decoders and the
enable time of the memory usually are less than
the typical access time of the memory. This means
that the effective system delay introduced by the
decoders is negligible.

LM6132,LM6134
Dual and Quad Low Power 10 MHz Rail-to-Rail I/O
Operational Amplifiers
General Description
The LM6132/34 provides new levels of speed vs. power
performance in applications where low voltage supplies or
power limitations previously made compromise necessary.
With only 360 μA/amp supply current, the 10 MHz gainbandwidth
of this device supports new portable applications
where higher power devices unacceptably drain battery life.
The LM6132/34 can be driven by voltages that exceed both
power supply rails, thus eliminating concerns over exceeding
the common-mode voltage range. The rail-to-rail output
swing capability provides the maximum possible dynamic
range at the output. This is particularly important when operating
on low supply voltages. The LM6132/34 can also
drive large capacitive loads without oscillating.
Operating on supplies from 2.7V to over 24V, the LM6132/34
is excellent for a very wide range of applications, from battery
operated systems with large bandwidth requirements to
high speed instrumentation.

LM2676
June 29, 2012
SIMPLE SWITCHER®® High Efficiency 3A Step-Down
Voltage Regulator
General Description
The LM2676 series of regulators are monolithic integrated
circuits which provide all of the active functions for a stepdown
(buck) switching regulator capable of driving up to 3A
loads with excellent line and load regulation characteristics.
High efficiency (>90%) is obtained through the use of a low
ON-resistance DMOS power switch. The series consists of
fixed output voltages of 3.3V, 5V and 12V and an adjustable
output version.
The SIMPLE SWITCHER concept provides for a complete
design using a minimum number of external components. A
high fixed frequency oscillator (260KHz) allows the use of
physically smaller sized components. A family of standard inductors
for use with the LM2676 are available from several
manufacturers to greatly simplify the design process.
The LM2676 series also has built in thermal shutdown, current
limiting and an ON/OFF control input that can power
down the regulator to a low 50μA quiescent current standby
condition. The output voltage is guaranteed to a ±2% tolerance.
The clock frequency is controlled to within a ±11%
tolerance.
Features
■ Efficiency up to 94%
■ Simple and easy to design with (using off-the-shelf
external components)
■ 150 mΩ DMOS output switch
■ 3.3V, 5V and 12V fixed output and adjustable (1.2V to
37V ) versions
■ 50μA standby current when switched OFF
■ ±2%maximum output tolerance over full line and load
conditions
■ Wide input voltage range: 8V to 40V
■ 260 KHz fixed frequency internal oscillator
■ −40 to +125°C operating junction temperature range
Applications
■ Simple to design, high efficiency (>90%) step-down
switching regulators
■ Efficient system pre-regulator for linear voltage regulators

LM158,LM258,LM2904,LM358 Texas Instruments TI pdf datasheet download
LM158,LM258,LM2904,LM358
Low Power Dual Operational Amplifiers
General Description
The LM158 series consists of two independent, high gain,
internally frequency compensated operational amplifiers
which were designed specifically to operate from a single
power supply over a wide range of voltages. Operation from
split power supplies is also possible and the low power
supply current drain is independent of the magnitude of the
power supply voltage.
Application areas include transducer amplifiers, dc gain
blocks and all the conventional op amp circuits which now
can be more easily implemented in single power supply
systems. For example, the LM158 series can be directly
operated off of the standard +5V power supply voltage which
is used in digital systems and will easily provide the required
interface electronics without requiring the additional ±15V
power supplies.
The LM358 and LM2904 are available in a chip sized package
(8-Bump micro SMD) using National’s micro SMD package
technology.
Unique Characteristics
n In the linear mode the input common-mode voltage
range includes ground and the output voltage can also
swing to ground, even though operated from only a
single power supply voltage.
n The unity gain cross frequency is temperature
compensated.
n The input bias current is also temperature compensated.
Advantages
n Two internally compensated op amps
n Eliminates need for dual supplies
n Allows direct sensing near GND and VOUT also goes to
GND
n Compatible with all forms of logic
n Power drain suitable for battery operation
Features
n Available in 8-Bump micro SMD chip sized package,
(See AN-1112)
n Internally frequency compensated for unity gain
n Large dc voltage gain: 100 dB
n Wide bandwidth (unity gain): 1 MHz
(temperature compensated)
n Wide power supply range:
— Single supply: 3V to 32V
— or dual supplies: ±1.5V to ±16V
n Very low supply current drain (500 μA)—essentially
independent of supply voltage
n Low input offset voltage: 2 mV
n Input common-mode voltage range includes ground
n Differential input voltage range equal to the power
supply voltage
n Large output voltage swing

LM10
Operational Amplifier and Voltage Reference
General Description
The LM10 series are monolithic linear ICs consisting of a
precision reference, an adjustable reference buffer and an
independent, high quality op amp.
The unit can operate from a total supply voltage as low as
1.1V or as high as 40V, drawing only 270μA. A complementary
output stage swings within 15 mV of the supply terminals
or will deliver ±20 mA output current with ±0.4V saturation.
Reference output can be as low as 200 mV.
The circuit is recommended for portable equipment and is
completely specified for operation from a single power cell.
In contrast, high output-drive capability, both voltage and
current, along with thermal overload protection, suggest it in
demanding general-purpose applications.
The device is capable of operating in a floating mode, independent
of fixed supplies. It can function as a remote comparator,
signal conditioner, SCR controller or transmitter for
analog signals, delivering the processed signal on the same
line used to supply power. It is also suited for operation in a
wide range of voltage- and current-regulator applications,
from low voltages to several hundred volts, providing greater
precision than existing ICs.
This series is available in the three standard temperature
ranges, with the commercial part having relaxed limits. In
addition, a low-voltage specification (suffix “L”) is available in
the limited temperature ranges at a cost savings.
Features
n input offset voltage: 2.0 mV (max)
n input offset current: 0.7 nA (max)
n input bias current: 20 nA (max)
n reference regulation: 0.1% (max)
n offset voltage drift: 2μV/°C
n reference drift: 0.002%/°C

different sets of peripherals targeted for various applications. The architecture, combined with five low power
modes is optimized to achieve extended battery life in portable measurement applications. The device features
a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that attribute to maximum code efficiency.
The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 6 μs.
The MSP430x13x and the MSP430x14x(1) series are microcontroller configurations with two built-in 16-bit

LM27222
High-Speed 4.5A Synchronous MOSFET Driver
General Description
The LM27222 is a dual N-channel MOSFET driver designed
to drive MOSFETs in push-pull configurations as typically
used in synchronous buck regulators. The LM27222 takes
the PWM output from a controller and provides the proper
timing and drive levels to the power stage MOSFETs. Adaptive
shoot-through protection prevents damaging and efficiency
reducing shoot-through currents, thus ensuring a robust
design capable of being used with nearly any MOSFET.
The adaptive shoot-through protection circuitry also reduces
the dead time down to as low as 10ns, ensuring the highest
operating efficiency. The peak sourcing and sinking current
for each driver of the LM27222 is about 3A and 4.5Amps
respectively with a Vgs of 5V. System performance is also
enhanced by keeping propagation delays down to 8ns. Efficiency
is once again improved at all load currents by supporting
synchronous, non-synchronous, and diode emulation
modes through the LEN pin. The minimum output pulse
width realized at the output of the MOSFETs is as low as
30ns. This enables high operating frequencies at very high
conversion ratios in buck regulator designs. To support low
power states in notebook systems, the LM27222 draws only
5μA from the 5V rail when the IN and LEN inputs are low or
floating.
Features
n Adaptive shoot-through protection
n 10ns dead time
n 8ns propagation delay
n 30ns minimum on-time
n 0.4Ω pull-down and 0.9Ω pull-up drivers
n 4.5A peak driving current
n MOSFET tolerant design
n 5μA quiescent current
n 30V maximum input voltage in buck configuration
n 4V to 6.85V operating voltage
n SO-8 and LLP packages
Applications
n High Current Buck And Boost Voltage Converters
n Fast Transient DC/DC Power Supplies
n Single Ended Forward Output Rectification
n CPU And GPU Core Voltage Regulators

LM317 3-TERMINAL ADJUSTABLE REGULATOR
FEATURES
· Output Voltage Range Adjustable From 1.25 V
· Thermal Overload Protection to 37 V
· Output Safe-Area Compensation
· Output Current Greater Than 1.5 A
· Internal Short-Circuit Current Limiting
DESCRIPTION/ORDERING INFORMATION
The LM317 is an adjustable three-terminal positive-voltage regulator capable of supplying more than 1.5 A over
an output-voltage range of 1.25 V to 37 V. It is exceptionally easy to use and requires only two external resistors
to set the output voltage. Furthermore, both line and load regulation are better than standard fixed regulators.
In addition to having higher performance than fixed regulators, this device includes on-chip current limiting,
thermal overload protection, and safe operating-area protection. All overload protection remains fully functional,
even if the ADJUST terminal is disconnected.
The LM317 is versatile in its applications, including uses in programmable output regulation and local on-card
regulation. Or, by connecting a fixed resistor between the ADJUST and OUTPUT terminals, the LM317 can
function as a precision current regulator. An optional output capacitor can be added to improve transient
response. The ADJUST terminal can be bypassed to achieve very high ripple-rejection ratios, which are difficult
to achieve with standard three-terminal regulators.

LM158/LM258/LM358/LM2904 Low Power Dual Operational Amplifiers
Literature Number:
General Description
The LM158 series consists of two independent, high gain,
internally frequency compensated operational amplifiers
which were designed specifically to operate from a single
power supply over a wide range of voltages. Operation from
split power supplies is also possible and the low power
supply current drain is independent of the magnitude of the
power supply voltage.
Application areas include transducer amplifiers, dc gain
blocks and all the conventional op amp circuits which now
can be more easily implemented in single power supply
systems. For example, the LM158 series can be directly
operated off of the standard +5V power supply voltage which
is used in digital systems and will easily provide the required
interface electronics without requiring the additional ±15V
power supplies.
The LM358 and LM2904 are available in a chip sized package
(8-Bump micro SMD) using National’s micro SMD package
technology.
Unique Characteristics
n In the linear mode the input common-mode voltage
range includes ground and the output voltage can also
swing to ground, even though operated from only a
single power supply voltage.
n The unity gain cross frequency is temperature
compensated.
n The input bias current is also temperature compensated.
Advantages
n Two internally compensated op amps
n Eliminates need for dual supplies
n Allows direct sensing near GND and VOUT also goes to
GND
n Compatible with all forms of logic
n Power drain suitable for battery operation
Features
n Available in 8-Bump micro SMD chip sized package,
(See AN-1112)
n Internally frequency compensated for unity gain
n Large dc voltage gain: 100 dB
n Wide bandwidth (unity gain): 1 MHz

shunt monitors. Wide input common-mode voltage range,
low quiescent current, and tiny SOT23 packaging enable use
in a variety of applications.
Input common-mode and power-supply voltages are independent
and can range from 2.7V to 36V for the INA138 and
2.7V to 60V for the INA168. Quiescent current is only 25μA,
which permits connecting the power supply to either side of
the current measurement shunt with minimal error.
The device converts a differential input voltage to a current
output. This current is converted back to a voltage with an
external load resistor that sets any gain from 1 to over 100.
Although designed for current shunt measurement, the circuit
invites creative applications in measurement and level shifting.
Both the INA138 and INA168 are available in SOT23-5 and
are specified for the –40°C to +125°C temperature range.

DESCRIPTION
The INA122 is a precision instrumentation amplifier
for accurate, low noise differential signal acquisition.
Its two-op-amp design provides excellent performance
with very low quiescent current, and is ideal for
portable instrumentation and data acquisition systems.
The INA122 can be operated with single power supplies
from 2.2V to 36V and quiescent current is a mere
60mA. It can also be operated from dual supplies. By
utilizing an input level-shift network, input commonmode
range extends to 0.1V below negative rail (single
supply ground).
A single external resistor sets gain from 5V/V to
10000V/V. Laser trimming provides very low offset
voltage (250mV max), offset voltage drift (3mV/°C
max) and excellent common-mode rejection.
Package options include 8-pin plastic DIP and SO-8
surface-mount packages. Both are specified for the
–40°C to +85°C extended industrial temperature range.

23 bits is achieved through the use of a very low-noise input
amplifier at conversion rates up to 10Hz. Effective resolutions
of 20 bits can be maintained up to a sample rate of
1kHz through the use of the unique Turbo modulator mode
of operation. The dynamic range of the converters is further
increased by providing a low-noise programmable gain
amplifier with a gain range of 1 to 16 in binary steps.
The ADS1210 and ADS1211 are designed for high resolution
measurement applications in smart transmitters, industrial
process control, weigh scales, chromatography, and portable
instrumentation. Both converters include a flexible synchronous
serial interface that is SPI-compatible and also offers a
two-wire control mode for low cost isolation.
The ADS1210 is a single-channel converter and is offered in
both 18-pin DIP and 18-lead SOIC packages. The ADS1211
includes a 4-channel input multiplexer and is available in 24-
