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/4(per buffer). DocID8021 Rev 3 7/14 14 Electrical characteristics M74HC126 Figure 3.
