IN74HCT157A Datasheet - IK Semiconductor

TECHNICAL DATA IN74HCT157A Quad 2-Input Data Selectors/Multiplexer High-Performance Silicon-Gate CMOS The IN74HCT157A is identical in pinout to the LS/ALS157.

This device may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs.

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 leve
