I would like to change a 5V CAN transceiver on my board into a 3V3 CAN transceiver. Nevertheless as I am clearly not a specialist of the CAN protocol, I am afraid of doing a big mistake ! I think it will clearly make the communication less robust if I reduce the power supply to 3V3. The rate of error of communication will increase. In 5V I have already some errors.
Here are the two differents datasheet (If you know a better 3V3 CAN transceiver, I would be happy to hear it) :

Well what I see is the differential voltage and the common voltage between CANL and CANH is lower with a 3V3 tranceiver during the dominant and the recessive...
Actually, according to the datasheet, the differential voltage is not really affected ? ! And the voltage refered to the ground is a bit affected but no much as I thoough... What do you think about the difference in robustness between the two transceiver ? What are the other elements to pay attention ?
Thank you very much and have a nice day !
