1) 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 operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC/2 (per

Flip-Flop)

TEST CIRCUIT

CL = 50pF or equivalent (includes jig and probe capacitance)

RL = R1 = 500Ω or equivalent

RT = ZOUT of pulse generator (typically 50Ω)
