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,

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.
