1 Mbps CAN transceiver for the 3.3V rail
The 100 mV of receiver hysteresis cleans up the bus signal on long cable runs where common-mode noise creeps in. The 8-SOIC package is the standard footprint for CAN PHY on industrial and automotive PCBs — same land pattern as the older 5V parts, so a board originally laid out for a 5V transceiver can swap to this one if the MCU side moved to 3.3V.
