Description for the SN74AUP1T34

The SN74AUP1T34 device is a 1-bitnoninverting translator that uses two separate configurable power-supply rails. It is auni-directional translator from A to B. The A port is designed to trackVCCA. VCCA accepts supply voltages from 0.9 V to 3.6V. The B port is designed to track VCCB. VCCB acceptssupply voltages from 0.9 V to 3.6 V. This allows for low-voltage translation between 1-V, 1.2-V,1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes. The SN74AUP1T34 is also fully specified forpartial-power-down applications using Ioff. The Ioffcircuitry disables the outputs, preventing damaging current backflow through the device when it ispowered down.

The VCC isolation feature ensures that if VCCA input is at GND,the B port is in the high-impedance state. If VCCB input is at GND, anyinput to the A side does not cause the leakage current even floating.
