Note 1: Parameter guaranteed by design.
tosLH = |tpLHm − tpLHn|, tosHL = |tpHLm − tpHLn|
Note 2: 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 bit)
And the total CPD when n pcs.of flip flop operate can be gained by the following equation:
CPD (total) = 22 + 9·n
