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 inputs. A high level at
the strobe terminal forces the W output high and
the Y output low.
The SN54HC151 is characterized for operation
over the full military temperature range of –55°C
to125°C. The SN74HC151 is characterized for
operation from –40°C to 85°C.
