1 Maximum bus capacitance is limited to 400 pF.  
2 The SDA and SCL timing is measured with the input filters enabled. Switching off the input filters improves the transfer rate but has a negative effect on EMC behavior  
of the part.  
3 Input filtering on the SCL and SDA inputs suppress noise spikes that are less than 50 ns for fast mode.
