SN65HVD233: CANH and/or CANL shorted to GND

Takahashi-san,

Shorting the CAN bus to GND alone should not eventually cause damage, with the CAN short-circuit current limit it should keep the self-heating to a level that keeps the device from damage. The example you linked is the same here though in that it will be application-specific. The self heating could cause thermal shutdown, but it will be dependent on if the bus is being driven dominant, and the ambient temperature of the application. In either case, the CAN transceiver has dominant time out where the amount of time being driven dominant with a CAN bus short to GND will be very short, and likely not cause any thermal issues.
