CIN Input Capacitance 4 10 10 pF CPD Power Dissipation Capacitance (note 1) 12 pF 1) CPD isdefined as the value of the IC’sinternal equivalent capacitance which is calculated fromthe operating current consumption without load. (Referto Test Circuit).Average operating current can be obtained by the following equation. ICC(opr) = CPD • VCC • fIN +ICC/6 (per Gate) AC ELECTRICAL CHARACTERISTICS (Input tr =tf =3 ns) Symb ol Parameter Test Co nditi on Val ue Un it VCC (*) (V) CL (pF ) TA =25 oC -40 to 85 oC Min. Typ .
