8-INPUT DATA SELECTOR/MULTIPLEXER WITH 3-STATE OUTPUTS
High-Performance Silicon-Gate CMOS
The IN74HC251 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 highimpedance state. This 3-State feature allows the IN74HC251 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 μA
? High Noise Immunity Characteristic of CMOS Devices
