Product Number: MAX3491AE
Does the MAX3491AE have TVS diodes internal to the die and are they unidirectional. Are they connected on the transmitter pins and what is their power rating and break down voltage if so. We had a case were the transceiver was isolated and improper grounding caused a large potential difference between chassis and ground causing a possible TVS diode to conduct, burn out and short. If they were TVS diodes were they designed to fail high Z, open, or short? I know it is hard to predict their failure state, but curious if any design work has been done to get a direction as to their expected failure state.
