1. Parameter guaranteed by design. tOSLH = |tPLHm – tPLHn|, tOSHL = |tPHLm – tPHLn|.
2. CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load.
Averageoperating current can be obtained by the equation: ICC(OPR)=CPDVCCfin+ICC / 8(perbit).CPDisusedtodeterminetheno–load
