[1] Typical values are measured at nominal supply voltage.

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

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

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

PD = CPD × VCC 2 × fi + Σ(CL × VCC 2 × fo) where:

fi = input frequency in MHz;

fo = output frequency in MHz;

Σ(CL × VCC 2 × fo) = sum of outputs;

CL = output load capacitance in pF;

VCC = supply voltage in V.
