74AUP1T34
Low-power dual supply translating buffer
Rev. 6 — 28 January 2019
Product data sheet
1. General description
The 74AUP1T34 provides a single buffer with two separate supply voltages. Input A is designed
to track V
CC(A)
. Output Y is designed to track V
CC(Y)
. Both, V
CC(A)
and V
CC(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.
Schmitt trigger action at all inputs makes the circuit tolerant to slower input rise and fall times
across the entire V
CC
range from 1.1 V to 3.6 V. This device ensures a very low static and dynamic
power consumption across the entire V
CC
range from 1.1 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 and benefits
•
•
•
Wide supply voltage range from 1.1 V to 3.6 V
