The UT54ACS02E and UT54ACTS02E are quadruple, two-
input NOR gates. The circuits perform the Boolean functions
Y = A + B or Y = A B in positive logic.
The devices are characterized over the full HiRel temperature
range of -55C to +125C.

, the maximum product of load capacitance (per output buffer) times frequency should not exceed 3,765pF/
MHz.
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
SS
at
frequency of 1MHz and a signal amplitude of 50mV rms maximum.
6. Maximum allowable relative shift equals 50mV.
7. All specifications valid for the maximum radiation dose available for the respective device types.
8. Power dissipation specified per switching output.
9. Guaranteed by characterization, but not tested.
