Dynamic characteristics [1] tpd is the same as tPHL and tPLH. [2] ten is the same as tPZH and tPZL. [3] tdis is the same as tPHZ and tPLZ. [4] tt is the same as tTHL and tTLH. [5] CPD is used to determine the dynamic power dissipation (PD in µW). PD =CPD × VCC2 × fi × N+ ∑(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; ∑(CL × VCC2 × fo) = sum of outputs.
