Package

This 1-bit noninverting translator uses two separate

configurable

power-supply

rails.

The

A

port

is

1.2 V to 3.6 V on A Port and

voltage from 1.2 V to 3.6 V. The B port is designed to

GND, All Outputs are in the High-Impedance State

1.65 V to 5.5 V. This allows for universal low-voltage

•

bidirectional translation between any of the 1.2-V,

1.5-V, 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes.
