DESCRIPTION
The UT54ACS244E is a performance and voltage enhanced
version of the UT54ACS244 non-inverting octal buffers and
line drivers which improve the performance and density of
three-state memory address drivers, clock drivers, and bus-ori-
ented receivers and transmitters.
The device is characterized over full military temperature range
of -55°C to +125°C.
