Absolute Maximum Ratings(Note 1) Recommended Operating
Conditions
Note 1: 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, and output/input loading variables. Fairchild does not
recommend operation of FACT circuits outside databook specifications.
DC Electrical Characteristics
Note 2: All outputs loaded; thresholds associated with output under test.
Note 3: Maximum test duration 2.0 ms; one output loaded at a time.
Note 4: Worst case package.
