โ€ข8-Line to 1-Line Multiplexers Can Perform
as:
Boolean Function Generators
Parallel-to-Serial Converters
Data Source Selectors
โ€ขPackage Options Include Plastic
Small-Outline Packages, Ceramic Chip
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 โˆ’55ยฐC
to 125ยฐC. The SN74F151B is characterized for
operation from 0ยฐ ยฐC to 70 C.
