Notes:
3. Parameter guaranteed by design. tOSLH = |tPLHmax – tPLHmin|; tOSHL = |tPHLmax – tPHLmin|.
4. 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).
