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.
