Hi Team,
We have a customer trying to understand the expected behavior of the SN65LVDS31DR driver chip when an overvoltage occurs on the supply. Assuming the device failed, is it possible for the supply voltage (which exceeds the absolute max rating) to be on the differential driver lines? If it is possible, is it likely? Is there something in the data sheet that indicates this?
The customer haven't experienced an overvoltage condition at this point but he is asking this question for internal design documentation purposes only.
I have checked the datasheet regarding this inquiry and found in Section 9.3.4 of the datasheet that the device's outputs have current sources but it is not clear if the supply voltage will appear in the differential driver lines once the current sources failed.
Regards,
Danilo
