74AUP3G34
Rev. 3 — 3 July 2017
Low-power triple buffer
Product data sheet
1
General description
The 74AUP3G34 is a triple buffer.
Schmitt trigger action at all inputs makes the circuit tolerant of slower input rise and fall
times.
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 a damaging backflow current through the device
when it is powered down.

The minimum input and output voltage ratings may be exceeded if the input and output current ratings are observed.
For VSSOP8 packages: above 110 °C the value of P
tot
derates linearly with 8.0 mW/K.
For XSON8 and XQFN8 packages: above 118 °C the value of P
