SN54F151B
8-Line to 1-Line Multiplexers Can Perform
as:
Boolean Function Generators
Parallel-to-Serial Converters
Data Source Selectors
Package Options Include Plastic

Carriers, and Standard Plastic and Ceramic
300-mil DIPs
description
These monolithic data selectors/multiplexers
provide full binary decoding to select one of eight
data sources. The strobe (G) input must be at a
low logic level to enable the data
selection/multiplexing function. A high level at the
strobe terminal forces the W output high and the
Y output low.
The SN54F151B is characterized for operation
over the full military temperature range of − 55°C
to 125°C. The SN74F151B is characterized for
operation from 0°C to 70°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The input voltage rating may be exceeded provided that the input current rating is observed.
