[1] tpd is the same as tPLH and tPHL.

[2] tt is the same as tTHL and tTLH.

[3] CPD is used to determine the dynamic power dissipation (PD in μW).

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.
