Recommended Operating

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.
