tpd is the same as tPHL and tPLH.

tt is the same as tTHL and tTLH.

CPD is used to determine the dynamic power dissipation (PD in W):

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;

 (C
