DESCRIPTION

The UT54ACS240 and the UT54ACTS240 are inverting octal

buffer and line drivers which improve the performance and den-

sity of three-state memory address drivers, clock drivers, and

bus-oriented receivers and transmitters.

The devices are characterized over full military temperature

range of -55

°C to +125°C.
