Introduction
The IN74HC157A is identical in pin out to the LS/ALS157. The device inputs are compatible with standard CMOS outputs; with pull up
resistors, they are compatible with LS/ALSTTL 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 non inverted form. A high level on the Output Enable input sets all four Y outputs to a low level.
Specification
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 2.0 to 6.0 V
Low Input Current: 1.0 μA
High Noise Immunity Characteristic of CMOS Devices
