Overview
The SN74AUP1T34-Q1 is a 1-bit noninverting voltage-level translator produced by Texas Instruments. This device is designed to facilitate unidirectional voltage translation between two separate configurable power-supply rails, making it ideal for interfacing devices or systems operating at different voltage levels. The translator supports supply voltages from 0.9 V to 3.6 V on both the A and B ports, enabling low-voltage translation between various voltage nodes such as 1 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V. The device is fully specified for partial-power-down applications and features VCC isolation and input hysteresis for improved performance and noise immunity.
