Description
SL74HC257
Quad 2-Input Data Selector/Multiplexer with 3-State Outputs
High-Performance Silicon-Gate CMOS
The SL74HC257 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 A or B inputs as d...
