SEMICONDUCTOR TECHNICAL DATA

High–Performance Silicon–Gate CMOS

J SUFFIX

CERAMIC PACKAGE

CASE 620–10

The MC54/74HC157A 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.

The HC157A is similar in function to the HC257 which has 3–state outputs.
