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 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: 1.0
