TECHNICAL DATA

INTEGRAL
Quad 2-Input Data Selectors/Multiplexer
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.
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 2.0 to 6.0 V
Low Input Current: 1.0
