Part Number: ISO7421


I just got a claim from a customer regarding communication problems which is caused by a defect of an ISO7421.

The electronic environment is between -20°C and 25°C (it's truck trailer with built in refrigerator) and is sealed with a protection paint. Ground shifts are at a maximum of 70V.

Is there any known issue with this kind of isolators? Is it possible to send the device in to TI for further analysis?

kind regards
