IN74ACT157 - Quad 2-1 Data Selector/Multiplexer
TECHNICAL DATA IN74ACT157 Quad 2-Input Data Selector/Multiplexer High-Speed Silicon-Gate CMOS The IN74ACT157 is identical in pinout to the LS/ALS157, HC/HCT157.
The IN74ACT157 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
