TECHNICAL DATA
IN74HC157A
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 µA • High Noise Immunity Characteristic of
CMOS Devices
