3 / 6 page 3 www.fairchildsemi.com 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. DC Electrical Characteristics AC Electrical Characteristics Note 3: CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load. Average operating current can be obtained by the equation: ICC (opr.) = CPD * VCC * fIN + ICC/2 (per decoder).
