Recommended Operating

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.
