AC Electrical Characteristics
Note 4: Parameter guaranteed by design.
tOSLH = |tPLHm tPLHn|.
tOSHL = |tPHLm tPHLn|.
Capacitance
Note 5: 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
