IN74HC157A Datasheet (IK Semiconductor) - Quad 2-1 Data Selector/Multiplexer

IN74HC157A, Quad 2-1 Data Selector/Multiplexer

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.
