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 exc eption, to e nsure that the system des ign is reliabl e over its power
supply, temperatu re, and output /input lo ading variable s. Fairch ild do es not
recomm end operation of FACT

circuits outside databo ok s pecificat ions.
DC Electrical Characteristics for AC
Note 3: All outputs loaded; thresholds on input associated with output under test.
Note 4: Maximum test du ration 2.0 m s, one output loaded at a time.
Note 5: IIN and ICC @ 3. 0V are gu aranteed t o be less th an or equa l to th e respectiv e limit @ 5. 5V VCC.
