IN74HC158A - Quad 2-1 Data Selector/Multiplexer
TECHNICAL DATA IN74HC158A Quad 2-Input Data Selectors/Multiplexers High-Performance Silicon-Gate CMOS The IN74HC158A is identical in pinout to the LS/ALS158.
The device inputs are compatible with standard CMOS outputs; with pullup 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 invertered form.
A high level on the Output Enable input sets all four Y outpu
