DESCRIPTION/ORDERING INFORMATION
This two-bit non-inverting translator is a bidirectional voltage-level translator and can be used to establish digital
switching compatibility between mixed-voltage systems. It uses two separate configurable power-supply rails,
with the A ports supporting operating voltages from 1.65 V to 3.6 V while it tracks the VCCA supply, and the B
ports supporting operating voltages from 2.3 V to 5.5 V while it tracks the VCCB supply. This allows the support of
both lower and higher logic signal levels while providing bidirectional translation capabilities between any of the
1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes.
When the output-enable (OE) input is low, all I/Os are placed in the high-impedance state, which significantly
reduces the power-supply quiescent current consumption.
To ensure the high-impedance state during power up or power down, OE should be tied to GND through a
pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.
