skew
[1] All typical values are measured at nominal VCC and Tamb = 25 °C.
[2] Skew between any two outputs of the same package switching in the same direction. This parameter is guaranteed by design.
[3] CPD is used to determine the dynamic power dissipation (PD in µW).
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 = number of inputs switching;
Σ(CL × VCC2 × fo) = sum of the outputs.
[4] The condition is VI = GND to VCC
