Note 1: Parameter guaranteed by design.

(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 latch)

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

CPD (total) = 21 + 8･n
