DESCRIPTION
The UT54ACS157 and the UT54ACTS157 are monolithic data
selectors/multiplexers. A 4-bit word is selected from one of two
sources and is routed to the four outputs. A separate strobe
input, G, is provided.
The devices are characterized over full military temperature
range of -55°C to +125°C.
