Not all "high voltage" transceivers share this; the more common case, I think, is internal TVS diodes with an assumed line resistance protecting the device from incoming surge voltage. The TCAN1051 seems to be the exception. But TI datasheets are notoriously mediocre, and it would be nice to see a more explicit statement on this. | |
