74AUP1T34
Low-power dual supply translating buffer
Rev. 01 -- 4 December 2006 Product data sheet

1. General description
The 74AUP1T34 is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS compatible TTL families. Schmitt trigger action at all inputs makes the circuit tolerant to slower input rise and fall times across the entire VCC range from 1.1 V to 3.6 V. This device ensures a 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 damaging backflow current through the device when it is powered down. The 74AUP1T34 provides a single buffer with two separate supply voltages. Input A is designed to track VCC(A). Output Y is designed to track VCC(Y). Both, VCC(A) and VCC(Y) accepts any supply voltage from 1.1 V to 3.6 V. This feature allows universal low voltage interfacing between any of the 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V voltage nodes.
