Note 2: Absolute maximum ratings are those values beyond which damage
to the device may occur. The databook specifications should be met, without
exception, to ensure that the system design is reliable over its power supply,
temperature, output/input loading variables. Fairchild does not recommend
operation of FACTcircuits outside databook specifications.
