All typical values are measured at Tamb =25 °C.
[2]
These typical values are measured at VCC = 3.3 V.

Skew between any two outputs of the same package switching in the same direction. This parameter is guaranteed by design.

CPD is used to determine the dynamic power dissipation (PD in W).
PD =CPD × VCC2 × fi × N+ Σ(CL × VCC2 × fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
VCC = supply voltage in V;
N = total load switching outputs;
