MC74HC157A Datasheet PDF – Data Selector / Multiplexer

Part Number: MC74HC157A

Function: Quad 2-Input Data Selectors / Multiplexers

Package: DIP, SOIC 16 Pin Type

Manufacturer: ON Semiconductor


MC74HC157A datasheet



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.


• 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 A

• High Noise Immunity Characteristic of CMOS Devices

• In Compliance with the Requirements Defined by JEDEC Standard No. 7A

• Chip Complexity: 82 FETs or 20.5 Equivalent Gates
