SL74HCT157 Quad 2-Input Data Selectors/Multiplexer High-Performance Silicon-Gate CMOS The SL74HCT157 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 level.
• TTL/NMOS Compatible Input Levels • Outputs Directly Interface to CMOS, NMOS, and TTL • Operating Voltage Range: 4.
5 to 5.
5 V • Low Input Current: 1.
