TECHNICAL DATA

IN74HC157A

Quad 2-Input Data Selectors/Multiplexer

The IN74HC157A is identical in pin out to the LS/ALS157. The device

inputs are compatible with standard CMOS outputs; with pull up resistors,

they are compatible with LS/ALSTTL 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 non inverted

form. A high level on the Output Enable input sets all four Y outputs to a low

level.

Outputs Directly Interface to CMOS, NMOS, and TTL

Operating Voltage Range: 2.0 to 6.0 V

Low Input Current: 1.0 mA
