pF

1. 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). CPD is used to determine the

no–load dynamic power consumption; PD = CPD  VCC2  fin + ICC  VCC.
