74AUP2G126
Rev. 11 — 3 July 2017
Low-power dual buffer/line driver; 3-state
Product data sheet
1
General description
The 74AUP2G126 provides the dual non-inverting buffer/line driver with 3-state output.
The 3-state output is controlled by the output enable input (nOE). A LOW level at pin
nOE causes the output to assume a high-impedance OFF-state. This device has the
input-disable feature, which allows floating input signals. The inputs are disabled when
the output enable input nOE is LOW.
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 a damaging backflow current through the device
when it is powered down.
