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

The KK74ACT157 is identical in pinout to the LS/ALS157, HC/HCT157. The KK74ACT157 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 µA; 0.1 µA @ 25°C
• Outputs Source/Sink 24 mA
