6. C_PD 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: I_CC(OPR) = C_PD  V_CC  f_in + I_CC/2 (per decoder). C_PD is used to determine the
no−load dynamic power consumption; P_D = C_PD  V_CC2  f_in + I_CC  V_CC.
