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 F/F). The total CPD when n pcs. of the Octal D Flip-Flop operates
can be calculated by the equation: CPD (total) 20 8n.
