[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 × VCC 2 × fi × N + Σ(CL × VCC 2 × 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;

Σ(CL × VCC 2 × fo) = sum of outputs.
