Overview
TECHNICAL DATA
KK74HC251A
8-Input Data Selector/Multiplexer with 3-State Outputs
High-Performance Silicon-Gate CMOS
The KK74HC251A is identical in pinout to the LS/ALS251.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs.
The device selects one of the eight binary Data Inputs, as determined by the Address Inputs.
The Output Enable pin must be at a low level for the selected data to appear at the outputs.
If Output Enable is high, the Y and the Y outputs are in the high-impedance state.
This 3-State feature allows the KK74HC251A to be used in bus-oriented systems.
• Outputs Directly Interface to CMOS, NMOS, and TT...
