(*) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load.

(Refer to Test Circuit). Average operting current can be obtained by the following equation. ICC(opr) = CPD

•VCC •fIN +ICC

TEST CIRCUIT ICC (Opr.)

INPUT TRANSITION TIME IS THE SAME AS THAT IN CASE OF SWITCHING CHARACTERISTICS TEST.
