Typical values are measured at nominal supply voltage (VCC = 3.3 V and VCC = 5.0 V). tpd is the same as tPLH and tPHL. 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.
