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 SN54HCT157 is characterized for operation
over the full military temperature range of –55
°
C
to 125
°
C. The SN74HCT157 is characterized for
operation from –40
°
C to 85
°
C.
