This two-bit non-inverting translator is a bidirectional voltage-level translator and canbe used to establish digital switching compatibility between mixed-voltage systems. It uses twoseparate configurable power-supply rails, with the A ports supporting operating voltages from 1.65V to 3.6 V while it tracks the VCCA supply, and the B ports supportingoperating voltages from 2.3 V to 5.5 V while it tracks the VCCB supply. Thisallows the support of both lower and higher logic signal levels while providing bidirectionaltranslation 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-impedancestate, 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 toGND through a pulldown resistor; the minimum value of the resistor is determined by thecurrent-sourcing capability of the driver.
