IN74HC151
8-INPUT DATA SELECTOR/MULTIPLEXER
High-Performance Silicon-Gate CMOS
The IN74HC151 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
