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.

PD
Note 3: C is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load. Average
PD
operating current can be obtained by the equation: I (opr.) = C * V * f + I /2 (per decoder).
