[1] Typical values are measured at Tamb = 25 °C and VCC = 1.8 V, 2.5 V, 2.7 V, 3.3 V and 5.0 V respectively.

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

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

PD = CPD × VCC 2 × fi × N + ∑(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;

∑(CL × VCC 2 × fo) = sum of outputs.
