[2] Typical values are measured at VCC = 3.3 V. [3] Typical values are measured at VCC = 5.0 V. [4] CPD is used to determine the dynamic power dissipation (PD in μW). P 2 2 D = CPD × VCC × fi × N + Σ(CL × VCC × fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; VCC = supply voltage in V; N = number of inputs switching; Σ(C 2 L × VCC × fo) = sum of outputs.
