Note 5: Parameter guaranteed by design. tOSLH |tPLHmax tPLHmin|; tOSHL |tPHLmax tPHLmin|.
Note 6: 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 bit).
