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/6 (per F/F)
And the total CPD when n pcs of Flip Flop operate can be gained by the following equation.
CPD (total) = 20 + 12･n
