8 / 17 page 74VCXHQ163245 8/17 Table 10: Capacitance 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 current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC/16 (per circuit) Figure 4: Test Circuit CL = 10/30pF or equivalent (includes jig and probe capacitance) RL = R1 = 500Ω or equivalent RT = ZOUT of pulse generator (typically 50Ω) Table 11: Waveform Symbol Value Symbol Parameter Test Condition Value Unit VCCA (V) VCCB (V) TA = 25 °C -40 to 85 °C Min.
