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

[2] Power dissipated from input supply (VCCI)

PD = CPD x VCCI 2 x fi x 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) x VCCO 2 x 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;
