DESCRIPTION
The UT54ACS02 and the UT54ACTS02 are quadruple, twoinput NOR gates. The circuits perform the Boolean functions
Y = A + B or Y = A B in positive logic.
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.
