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 TTL Operating Voltage Range: 2.0 to 6.0 V Low Input Current: 1.0 A High Noise Immunity Characteristic of CMOS Devices By Kodenshi Korea Corp.
