SN74AUP1T34-Q1 - 1-Bit Unidirectional Voltage-Level Translator, SN74AUP1T34-Q1

The SN74AUP1T34-Q1 device is a 1-bit noninverting translator that uses two separate configurable power-supply rails. It is a unidirectional translator from A to B. The A port is designed to track V_CCA. V_CCA accepts supply voltages from 0.9 V to 3.6 V. The B port is designed to track V_CCB. V_CCB accepts supply 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-Q1 is also fully specified for partial-power-down applications using I_off. The I_off circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.

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