5 Summary

3.3V and 5V CAN transceivers are interoperable because the high-speed CAN physical layer uses differential signaling that is the same for a 3.3V and 5V CAN transceiver. In addition, both the 3.3V and 5V CAN transceivers have the same wide common mode range accommodating not only the typical signaling but also providing wide margin for ground shift potential. For systems that can benefit from the advantages of 3.3V transceivers, such as simplified power supplies and lower power consumption, they offer clear advantages in their use either in a homogeneous 3.3V CAN network or in a mixed 3.3V and 5V CAN network.
