AC Electrical Characteristics Note 8: Parameter guaranteed by design. tOSLH |tPLH max tPLH min|; tOSHL |tPHL max tPHL min| Note 9: 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 F/F). The total CPD when n pcs. of the Octal D Flip-Flop operates can be calculated by the equation: CPD (total) 20 12n.
