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.
