Note 1: CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating
current consumption without load.
Average operating current can be obtained by the equation:
ICC (opr) = CPD･VCC･fIN + ICC
When the outputs drive a capacitive load, total current consumption is the sum of CPD, and ΔICC which is
obtained from the following formula:
