Note 2: Absolute maximum ratings are those values beyond which dam-
age 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 FACT circuits outside databook specifica-
tions.
