1. General description
The 74AUP2G157 is a single 2-input multiplexer which select data from two data inputs
(I0 and I1) under control of a common data select input (S). The state of the common data
select input determines the particular register from which the data comes. The output
(Y, Y
) presents the selected data in the true (non-inverted) and complement form. The
enable input (E
) is active LOW. When E is HIGH, the output Y is forced LOW and the
output Y
is forced HIGH regardless of all other input conditions.
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.
