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).
