CPD is used to determine the dynamic power dissipation (PD in μW). PD = CPD × VCC2 × fi × N + Σ(CL × VCC2 × fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; VCC = supply voltage in Volts; N = number of inputs switching; Σ(CL × VCC2 × fo) = sum of the outputs. 2. The condition is VI = GND to VCC.
