Quad 2-Input Data Selector/Multiplexer
High-Speed Silicon-Gate CMOS

The KK74AC157 is identical in pinout to the LS/ALS157, HC/HCT157. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS 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 noninvertered 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; 0.1µA @ 25°C
• High Noise Immunity Characteristic of CMOS Devices
• Outputs Source/Sink 24 mA
