Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operations sections of this data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
The ORCA Series 3+ FPSCs include circuitry designed to protect the chips from damaging substrate injection cur-
rents and to prevent accumulations of static charge. Nevertheless, conventional precautions should be observed
during storage, handling, and use to avoid exposure to excessive electrical stress.
