[1] tpd is the same as tPLZ and tPZL.

[2] 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.
