CAPACITIVE CHARACTERISTICS

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

TEST CIRCUIT

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

RT = ZOUT of pulse generator (typically 50Ω)

WAVEFORM : PROPAGATION DELAY TIME (f=1MHz; 50% duty cycle)
