MC74HC157A

Quad 2-Input Data

Selectors / Multiplexers

High–Performance Silicon–Gate CMOS

The MC74HC157A is identical in pinout to the LS157. The device

inputs are compatible with standard CMOS outputs; with pullup

resistors, they are compatible with LSTTL outputs.

This device routes 2 nibbles (A or B) to a single port (Y) as

determined by the Select input. The data is presented at the outputs in

noninverted form. A high level on the Output Enable input sets all four

Y outputs to a low level.
