SL74HC158 Datasheet (System Logic Semiconductor) - Quad 2-Input Data Selectors/Multiplexers

SL74HC158, Quad 2-Input Data Selectors/Multiplexers

SL74HC158 Quad 2-Input Data Selectors/Multiplexers High-Performance Silicon-Gate CMOS The SL74HC158 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 outputs to a high level
