DESCRIPTION
The UT54ACS151 and the UT54ACTS151 are data multiplex-
ers that provide full binary decoding to select one of eight data
sources. The strobe input, G, must be at a low logic level to
enable the inputs. A high level at the strobe terminal forces the
Y output high and the Y output low.
The devices are characterized over full military temperature
range of -55°C to +125°C.
