KK74HC257A Quad 2-Input Data Selector/Multiplexer

TECHNICAL DATA KK74HC257A Quad 2-Input Data Selector/Multiplexer with 3-State Outputs High-Performance Silicon-Gate CMOS The KK74HC257A is identical in pinout to the LS/ALS257. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. This device selects a (4-bit) nibble from either the .
