ADUM140x failure mode (by EOS, maybe)

A ADUM1400 has failed.

Regardless of input voltage, only one channel outputs high level.

The other three channels are operating normally.

I suspect the cause is that the input voltage has exceeded the absolute maximum rating or ESD.

Does ADUM1400 break down due to a large voltage or ESD?


Thank you.
