DESCRIPTION
The SN74AUP1T34 is a 1-bit non-inverting translator that uses two separate configurable power-supply rails. The
A port is designed to track VCCA. VCCA accepts supply voltages from 0.9 V to 3.6 V. The B port is designed to
track VCCB. VCCB accepts supply voltages from 0.9 V to 3.6 V. This allows for low-voltage bidirectional
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 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.
