[1] tpd is the same as tPLH and tPHL
[2] tt is the same as tTLH and tTHL
[3] CPD is used to determine the dynamic power dissipation (PD in μW).
PD = CPD x VCC2 x fi x N + Σ(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 load switching outputs;
Σ(CL x VCC2 x fo) = sum of the outputs.
