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/4 (per flip flop)
And the total CPD when n pcs of flip flop operate be gained by the following equation:
CPD (total)
= 28 + 17･n
