3 / 8 page 3 www.fairchildsemi.com Absolute Maximum Ratings(Note 2) Recommended Operating Conditions (Note 3) Note 2: 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 3: Unused inputs must be held HIGH or LOW. They may not float. DC Electrical Characteristics Noise Characteristics Note 4: Parameter guaranteed by design.
