SN74AUP1T34DSFR

The SN74AUP1T34 device is a 1-bit non-inverting translator that uses two separate configurable supply rails. It is a unidirectional translator from A to B. The A port is designed to track VCCA, which accepts supply voltages ranging from 0.9V to 3.6V. The B port is designed to track VCCB, which 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 to prevent damaging reverse current flow when the device 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 to the A side will not cause leakage current, even when floating.
