DESCRIPTION
The UT54ACS365 and UT54ACTS365 are non-inverting hex
buffer and line driver with three-state outputs. The output enables (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.

Notes:
1. Logic will not latchup during radiation exposure within the limits defined in the table.
2. Device storage elements are immune to SEU affects.
ABSOLUTE MAXIMUM RATINGS
Note:
1. Stresses outside the listed absolute maximum ratings may cause permanent damage to the device. This is a stress rating only, functional operation of the device
at these or any other conditions beyond limits indicated in the operational sections is not recommended. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
