Note:
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
