(tosLH = |tpLHm − tpLHn|, tosHL = |tpHLm − tpHLn|) Note 2: Parameter guaranteed by design. Note 3: CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption. 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 + 9・n |
