1. CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current

consumption without load. (Refer to Figure 5: Test circuit). Average operating current can be obtained by the following

equation: ICC(opr) = CPD x VCC x fIN + ICC/2 (per flip-flop).
