DESCRIPTION

TheHCC4051B, 4052B and 4053B (extended temperature
range) and HCF4051B, 4052B and 4053B
(intermediate temperature range) are monolithic integrated
circuits, available in 16-lead dual in-line
plastic or ceramic package and plastic micropackage.
HCC/HCF4051B, HCC/HCF4052B, and
HCC/HCF4053B analog multiplexers/demultiplexers
are digitally controlled analog switches having
low ON impedance and very low OFF leakage

current. These multiplexer circuits dissipate extremely
low quiescent power over the full VDD –VSS
and VDD –VEE supply-voltage ranges, independent
of the logic state of the control signals.When a-logic
”1” is present at the inhibit input terminal all channel
are off. The HCC/HCF4051B is a single 8-channel
multiplexer having three binary control inputs, A, B,
and C, and an inhibit input. The three binary signals
select 1 of 8 channels to be turned on, and connect
one of the 8 inputs to the output. The
HCC/HCF4052B is a differential 4-channel multiplexerhaving
twobinary control inputs, Aand B,and
an inhibit input. The two binary input signals select
1 of 4 pairs of channels to be turned on and connect
the analog inputs to the outputs. The
HCC/HCF4053B is a triple 2-channel multiplexer
having three separate digital control inputs, A, B,
and C, and an inhibit input. Each control input selects
one of a pair of channels which are connected
in a singlepole double-throw configuration.

CMOS Analog Multiplexers/Demultiplexers
with Logic Level Conversion

The CD4051B, CD4052B, and CD4053B analog multiplexers
are digitally-controlled analog switches having low ON
impedance and very low OFF leakage current. Control of
analog signals up to 20VP-P can be achieved by digital
signal amplitudes of 4.5V to 20V (if VDD-VSS = 3V, a
VDD-VEE of up to 13V can be controlled; for VDD-VEE level
differences above 13V, a VDD-VSS of at least 4.5V is
required). For example, if VDD = +4.5V, VSS = 0V, and
VEE = -13.5V, analog signals from -13.5V to +4.5V can be
controlled by digital inputs of 0V to 5V. These multiplexer
circuits dissipate extremely low quiescent power over the
full VDD-VSS and VDD-VEE supply-voltage ranges,
independent of the logic state of the control signals. When
a logic “1” is present at the inhibit input terminal, all
channels are off.

The CD4051B is a single 8-Channel multiplexer having three
binary control inputs, A, B, and C, and an inhibit input. The
three binary signals select 1 of 8 channels to be turned on,
and connect one of the 8 inputs to the output.
The CD4052B is a differential 4-Channel multiplexer having
two binary control inputs, A and B, and an inhibit input. The
two binary input signals select 1 of 4 pairs of channels to be
turned on and connect the analog inputs to the outputs.
The CD4053B is a triple 2-Channel multiplexer having three
separate digital control inputs, A, B, and C, and an inhibit
input. Each control input selects one of a pair of channels
which are connected in a single-pole, double-throw
configuration.
When these devices are used as demultiplexers, the
“CHANNEL IN/OUT” terminals are the outputs and the
“COMMON OUT/IN” terminals are the inputs.

Sanyo LB1846M, 1848M pdf datasheet


Overview

The LB1846M and LB1848M are 2-channel low-voltage,
low saturation voltage type bidirectional motor driver ICs
that are optimal for use as 2-phase stepping motor drivers
in printers, floppy disk drives, and cameras and other
portable equipment. The output circuits are of the bipolar
type, with pnp transistors in the upper side and npn
transistors in the lower side, and they achieve low
saturation output and low power characteristics despite
being provided in a miniature package.
Both of these IC products can directly control a motor
from signals from a microcontroller. The LB1846M is
optimal for 1-2 phase excitation drive for 2-phase stepping
motors using 4-input logic (IN1, IN2, IN3, and IN4) and
the LB1848M is optimal for 2-phase excitation drive for
2-phase stepping motors using 3-input logic (ENA, IN1,
and IN2).
Another point is that these ICs include built-in thermal
shutdown circuits so that IC scorching or burning is
prevented in advance even if the IC outputs are shorted.
Additionally, the MFP-10S miniature package used
supports reduced-space mounting.

Features

• Optimal for 1-2 phase excitation drive for 2-phase
stepping motors (LB1846M)
• Optimal for 2 phase excitation drive for 2-phase
stepping motors (LB1848M)
• Low saturation voltage. VO(sat) = 0.55 V typical at IO =
400 mA
• Standby current: zero
• Thermal shutdown circuit
• Miniature package: MFP-10S (6.5 ´ 5.1 mm)
• Through-current prevention circuit (LB1848M only)
• “Soft off” function that reduces power supply line noise
when switching from drive to standby modes. (Requires
the use of one external capacitor.) (LB1848M only)
• No limitations on the magnitude relationship between
the power supply voltage (VCC) and the input voltage
(VIN)
