74AUP2G126
Low-power dual buffer/line driver; 3-state
Rev. 05 — 2 February 2009
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.
