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/4 (per gate)
