[1] CPD is used to determine the dynamic power dissipation (PD in μW).

[2] Power dissipated from input supply (VCCI):

PD = CPD × VCCI 2 × fi × N where:

CPD = power dissipation capacitance of the input supply;

VCCI = input supply voltage in V;

fi = input frequency in MHz;

N = number of inputs switching.

[3] Power dissipated from output supply (VCCO):

PD = (CL + CPD) × VCCO 2 × fo where:

CL = load capacitance in pF;

CPD = power dissipation capacitance of the output supply;

VCCO = output supply voltage in V;

fo = output frequency in MHz.
