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

[2] Typical values are measured at VCC = 3.3 V.

[3] Typical values are measured at VCC = 5.0 V.

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

PD = CPD x VCC2 x fi + 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;

Σ(CL x VCC2 x fo) = sum of the outputs.
