[1] Typical values are measured at nominal supply voltage (VCC = 3.3 V and VCC = 5.0 V).

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

[3] tpd is the same as tPHL only.

[4] 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 inputs switching;

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