DESCRIPTION
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.
