CPD capacitance
[1] All typical values are measured at Tamb = 25 °C. [2] tpd is the same as tPLH and tPHL. [3] tt is the same as tTLH and tTHL. [4] 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 V; N = number of inputs switching; Σ(CL × VCC2 × fo) = sum of outputs.
