[1] 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 Volts;
N = number of inputs switching;
Σ(CL × VCC2 × fo) = sum of the outputs.
[2] The condition is VI = GND to VCC − 1.5 V.
