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.
