TECHNICAL DATA
8-Input Data Selector/Multiplexer
High-Speed Silicon-Gate CMOS
KK74AC151
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
