TECHNICAL DATA
IN74HC151A
8-Input Data Selector/Multiplexer
High-Performance Silicon-Gate
CMOS
The IN74HC151A 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
ORDERING INFORMATION IN74HC151AN Plastic IN74HC151AD SOIC TA = -55° to 125° C for all packages
