Note (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 / 8 (per F/F).
And the total CPD when n pcs. of Flip-Flop operate can be gained by the following equation: CPD (total)=20+10 • n.
