Note 9: 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). The total CPD when n pcs. of the octal D Flip-Flop operates
can be calculated by the equation: CPD(total) = 20 + 12m.
