SN74AUP1T34DCKR

The SN74AUP1T34 device is a 1-bit non-inverting buffer with two independent configurable power rails. It is a unidirectional translator from A to B. The A port is designed to track VCCA. VCCA accepts supply voltages ranging from 0.9V to 3.6V. The B port is designed to track VCCB. VCCB accepts supply voltages ranging from 0.9V to 3.6V. This enables low-voltage translation between 1V, 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V voltage nodes. In addition, the SN74AUP1T34 is fully suitable for partial power-down applications using Ioff. The Ioff circuit disables the outputs, preventing reverse current flow that could damage the device when it is powered down. The VCC isolation feature ensures that the B port is in a high-impedance state when the VCCA input is at GND. If the VCCB input is at GND, any input on the A side will not cause leakage current, even when floating.

Applications

• Enterprise
