DESCRIPTION
The UT54ACS244 and the UT54ACTS244 are non-inverting
octal buffer and line drivers which improve the performance and
density 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.
