TECHNICAL DATA
KK74HC157A
Quad 2-Input Data Selectors/Multiplexer
The KK74HC157A 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.
