DESCRIPTION
The UT54ACS253 and the UT54ACTS253 are 1-line to 4-line
multiplexers that contain drivers to supply full binary decoding.
Separate output control inputs are provided for each of the two
four-line sections.
Use the three-state outputs to drive data lines in bus-organized
systems. With all but one of the common outputs disabled the
low-impedance of the single enable output will drive the bus
line to a high or low logic level. Each output has its own strobe
(G).
The devices are characterized over full military temperature
range of -55°C to +125°C.
