TECHNICAL DATA
IN74AC157
Quad 2-Input Data Selector/Multiplexer
High-Speed Silicon-Gate
CMOS
The IN74AC157 is identical in pinout to the LS/ALS157, HC/HCT157.
The device inputs are compatible with standard
CMOS outputs; with pullup resistors, they are compatible with LS/ALS 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 noninvertered form.
A high level on the Output Enable input sets all four Y outputs to a low level.
