ADUM3160 transient maximum ratings

Hello,

 

We are using common mode chokes at USB data lines for EMC purposes. But they distort the signal at EOP signalization that is not differential (USB 2.0). This distortions is causing some spikes.

 

The datasheet of ADUM3160, in table 7, show the absolute maximum ratings for IC pins. Several ICs have higher limits for transients, specifying maximum voltage level and duration time. For transient spikes should we consider these limits or higher limits are applicable? Where can I find them?

 

Thanks
