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).

V_SS

The devices are characterized over full military temperature

range of -55°C to +125°C.
