Conditions
Note 2: Absolute maximum ratings are those values beyond which damage
to the device may occur. The databook specifications should be met, with-
out exception, to ensure that the system design is reliable over its power
supply, temperature, output/input loading variables. Fairchild does not rec-
ommend operation of FACT
