CPD

(Note)

―

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/8 (per F/F)

And the total CPD when n pcs. of F/F operate can be gained by the following equation:

CPD (total) = 22 + 12·n
