SEMICONDUCTOR TECHNICAL DATA

Quad 2-Input Data

Selectors/Multiplexers

High–Performance Silicon–Gate CMOS

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.

•

Output Drive Capability: 10 LSTTL Loads

Outputs Directly Interface to CMOS, NMOS, and TTL

Operating Voltage Range: 2.0 to 6.0 V

Low Input Current: 1.0

µA

High Noise Immunity Characteristic of CMOS Devices

In Compliance with the Requirements Defined by JEDEC Standard

No. 7A
