IN74HC151A
TECHNICAL DATA
8-Input Data Selector/Multiplexer
High-Performance Silicon-Gate CMOS
The IN74HC151A is identical in pinout to the LS/ALS151. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible 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
