Absolute Maximum Ratings(Note 1) Recommended Operating
Conditions
(Note 2)
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 circuits outside the databook specifications.
Note 2: Unused inputs must be held HIGH or LOW. They may not float.
