Noise Characteristics
Note 3: Parameter guaranteed by design.
AC Electrical Characteristics
Note 4: Parameter guaranteed by design. tOSLH |tPLH max  tPLH min|; tOSHL |tPHL max  tPHL min|
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/8 (per Bit).
