IN74AC158 Datasheet (IK Semiconductor) - Quad 2-1 Data Selector/Multiplexer

IN74AC158, Quad 2-1 Data Selector/Multiplexer

TECHNICAL DATA Quad 2-Input Data Selector/Multiplexer High-Speed Silicon-Gate CMOS The IN74AC158 is identical in pinout to the LS/ALS158, HC/HCT158.

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 invertered form.

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