(*) 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 the
CPD when N pcs of Flip Flop operate, can be gained by following equation:
CPD (TOTAL) = 32 + 34 x n [pF] (for HCT373); 30 + 22 x n [pF] (for HCT533)
