Carriers (FK), and Standard Plastic (N) and
Ceramic (J) 300-mil DIPs
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.
