capacitance
[1] tpd is the same as tPHL and tPLH.
[2] tt is the same as tTHL and tTLH.
[3] CPD is used to determine the dynamic power dissipation (PD in W).
PD = CPD VCC2 fi + (CL VCC2 fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
(CL VCC2 fo) = sum of outputs;
CL = output load capacitance in pF;
VCC = supply voltage in V.
