8-Input Data Selector/Multiplexer
High-Speed Silicon-Gate CMOS
The KK74AC151 is identical in pinout to the LS/ALS151, HC/HCT151. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS outputs. The device selects one of the eight binary Data Inputs, as determined by the Address Inputs. The Strobe pin must be at a low level for the selected data to appear at the outputs. If Strobe is high, the Y output is forced to a low level and the Y output is forced to a high level. Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 2.0 to 6.0 V Low Input Current: 1.0 µA; 0.1 µA @ 25°C High Noise Immunity Characteristic of CMOS Devices Outputs Source/Sink 24 mA
