All typical values are measured at Tamb = 25 C. tpd is the same as tPLH and tPHL. tt is the same as tTLH and tTHL. CPD is used to determine the dynamic power dissipation (PD in W). PD = CPD x VCC2 x fi x N + (CL x VCC2 x 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 x VCC2 x fo) = sum of outputs.
