(*) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load.
(Refer to Test Circuit). Average operting current can be obtained by the following equation. ICC(opr) = CPD •VCC •fIN + ICC/8 (per FLIP-FLOP) and CPD
when N pcs of FLIP-FLOP operate, can be gained by following equation: CPD (TOTAL) = 38 + 18 x N (pF)
