description
These monolithic data selectors/multiplexers
contain inverters and drivers to supply full data
selection to the four output gates. A separate
strobe (G) input is provided. A 4-bit word is
selected from one of two sources and is routed to
the four outputs. The ’HC157 present true data.
The SN54HC157 is characterized for operation
over the full military temperature range of –55
°C
to 125
°C. The SN74HC157 is characterized for
operation from –40
°C to 85°C.
