TCAN4550: TCAN4550 can support 5V system?

Hi Kevin,

Yes, TCAN4550 is designed to work on a CAN bus with other 5V CAN transceivers that meet the ISO 11898-2 specification. The device itself requires a Vsup supply between 5.5V and 24V for proper operation. 

Let me know if you have any more questions.

Regards,
Eric Schott
