TECHNICAL DATA
8-Input Data Selector/Multiplexer
High-Performance Silicon-Gate CMOS
KK74HC151A
The KK74HC151A is identical in pinout to the LS/ALS151. 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 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
• High Noise Immunity Characteristic of CMOS Devices
