8-Line to 1-Line Multiplexers Can Perform
as:
Boolean Function Generators
Parallel-to-Serial Converters
Data Source Selectors
Package 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
selection/multiplexing function. A high level at the
strobe terminal forces the W output high and the
Y output low.
