1. General description

The 74AUP1T34 is a single dual supply translating buffer. Input A is referenced to VCC(A) and

output Y is referenced to VCC(Y). Schmitt-trigger action at all inputs makes the circuit tolerant

of slower input rise and fall times. This device ensures very low static and dynamic power

consumption across the entire VCC range from 1.1 V to 3.6 V. This device is fully specified for

partial power down applications using IOFF. The IOFF circuitry disables the output, preventing the

potentially damaging backflow current through the device when it is powered down.
