8-Input Data
Selector/Multiplexer
High–Performance Silicon–Gate CMOS
The MC74HC151 is identical in pinout to the LS151. The device inputs are
compatible with standard CMOS outputs; with pullup resistors, they are
compatible with LSTTL outputs.
This 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.
The HC151 is similar in function to the HC251 which has 3–state outputs.
• Output Drive Capability: 10 LSTTL Loads
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2 to 6 V
• Low Input Current: 1 µA
• High Noise Immunity Characteristic of CMOS Devices
• In Compliance with the Requirements Defined by JEDEC Standard
No. 7A
• Chip Complexity: 132 FETs or 33 Equivalent Gates
