description
These
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
′ALS157A and SN74AS157 present true
data. The
′ALS158 and SN74AS158 present
inverted data to minimize propagation delay time.
The
SN54ALS157A
and
SN54ALS158
are
characterized for operation over the full military
temperature range of 55
°C to 125°C. The
SN74ALS157A, SN74ALS158, SN74AS157, and
SN74AS158 are characterized for operation from
0
°C to 70°C.
