CIN Input Capacitance 5.0 4.5 pF CPD Power Dissipation Capacitance (note 1) 5.0 fIN = 10 MHz 35 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 operting current can be obtained by the following equation. ICC(opr) = CPD • VCC • fIN +ICC/n(per circuit) AC ELECTRICAL CHARACTERISTICS (CL = 50 pF, RL = 500 Ω, Input tr =tf =3 ns) Symb ol Parameter T est Con ditio n Valu e Un it VCC (V) TA =25 oC -40 to 85 oC Min.
