CPD Power Dissipation Capacitance (Per Inverter) (Note 1) 18 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/6 (per buffer). CPD is used to determine the no−load dynamic power consumption; P 2 D = CPD VCC fin + ICC VCC.
