3 / 10 page 3 www.fairchildsemi.com Absolute Maximum Ratings(Note 2) Recommended Operating 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, and output/input loading variables. Fairchild does not recommend operation of FACT ¥ circuits outside databook specifications. DC Electrical Characteristics for AC Note 3: All outputs loaded; thresholds on input associated with output under test. Note 4: Maximum test duration 2.0 ms, one output loaded at a time. Note 5: IIN and ICC @ 3.0V are guaranteed to be less than or equal to the respective limit @ 5.5V VCC.
