The UT54ACS365 and UT54ACTS365 are non-inverting hex
buffer and line driver with three-state outputs. The output en-
ables (OE1 and OE2) control the three-state outputs. If OE1 or
OE2 is high, the outputs will be in a high impedance state. For
data, both OE1 and OE2 must be low.
The devices are characterized over full military temperature
range of -55°C to +125°C.

4. Not more than one output may be shorted at a time for maximum duration of one second.
5. Capacitance measured for initial qualification and when design changes may affect the value. Capacitance is measured between the designated terminal and V
