Note 3: 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 varai-
bles. Fairchild does not recommend operation outside databook specifica-
tions.
Note 4: Unused inputs must be held HIGH or LOW. They may not float.
