Absolute Maximum Ratings(Note 1)
Recommended Operating
Conditions (Note 2)
Note 1: Absolute Maximum Ratings are values beyond which the device
may be damaged or have its useful life impaired. The databook specifica-
tions should be met, without exception, to ensure that the system design is
reliable over its power supply, temperature, and output/input loading vari-
ables. Fairchild does not recommend operation outside databook specifica-
tions.
Note 2: Unused inputs must be held HIGH or LOW. They may not float.
