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.
Average operating current can be obtained by the equation: ICC(OPR) = CPD VCC fin + ICC/8 (per bit). CPD is used to determine the noload
dynamic power consumption; PD = CPD VCC2 fin + ICC VCC.
