74AUP2G34
Low-power dual buffer
Rev. 02 — 31 January 2008
Product data sheet
1. General description
The 74AUP2G34 provides two low-power, low-voltage buffers.
Schmitt trigger action at all inputs makes the circuit tolerant to slower input rise and fall
times across the entire V
CC
range from 0.8 V to 3.6 V.
This device ensures a very low static and dynamic power consumption across the entire
V
CC
range from 0.8 V to 3.6 V.
This device is fully specified for partial power-down applications using I
OFF
.
The I
OFF
circuitry disables the output, preventing the damaging backflow current through
the device when it is powered down.
2. Features
I
Wide supply voltage range from 0.8 V to 3.6 V
