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 VCC range from 0.8 V to 3.6 V. This device ensures a very low static and dynamic

power consumption across the entire VCC range from 0.8 V to 3.6 V.

This device is fully specified for partial power-down applications using IOFF. The IOFF circuitry

disables the output, preventing the damaging backflow current through the device when it is

powered down.
