Does TI have any CAN transceiver which can operate with 3V~5V VCC range?

Other Parts Discussed in Thread: TCAN332

Hello guys,

One of my customers is looking for a CAN transceiver which can operate with 3V~5V VCC range.

Does TI have any CAN transceiver which can operate with 3V~5V VCC range? 
Or does TI have any plan to release such device in the future?

Your reply would be much appreciated.

Best regards,
Kazuya.

    No, the CAN transceivers either work only at 3.3 V, or have a minimum voltage of 5 V:

    (The "1.71 to 5.5" entry is for the logic voltage of some isolators; those also require 5 V for the CAN side.)

    Thanks Clemens!

    Hi Kazuya-san,

    Unfortunately we do not have any CAN transceivers that can work within this wide of a range. Due to the heavy focus on EMC performance for 5V transceivers the supply range for these devices is limited to ensure that the common mode remains stable when operating within a network with other 5V supplied devices. 

    There are 3.3V supplied transceivers that are pin compatible with 5V devices so they can be easily swapped in the BOM for applications with different available supplies. The TCAN332 (3.3V supplied) for example is pin compatible with the TCAN1044A (5V supplied). Would this be suitable for your intended applications? 

    Regards,
