Mixed 3.3V and 5V CAN transceivers possible?

Post by abaldur » Mon 27. Apr 2020, 10:23

Hi

I'm using the PCAN-PCI Express board for communication with a 3.3V CAN bus.

The PCAN-PCI Express uses the NXP PCA82C251 CAN transceiver which is 5V as far as I can see.

Will this cause any issues with reliability on the network?

Anything to be especially aware of?

Best Regards,

Hello,

The PCAN-PCIe use a High Speed compatible Transceiver (ISO 11898-2).

Please check if the transceiver of the 3.3 V CAN bus is compatible with ISO 11898-2 as well.

We do not know of any issues regarding this if both transceivers are ISO 11898-2 compliant.


Best Regards

Marvin

Hi Marvin

Thanks for the quick reply.

My 3.3V CAN transceiver happens to be ISO 11898-2 compatible.

So I will assume that things to work together :)
