MC74HC151A
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.
Features
• 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 mA
• High Noise Immunity Characteristic of CMOS Devices
• NLV Prefix for Automotive and Other Applications Requiring
Unique Site and Control Change Requirements; AEC−Q100
Qualified and PPAP Capable
• These are Pb−Free Devices
