11.3.1 ISO11898 Compliance of TCAN33x Family of 3.3-V CAN Transceivers Introduction
Many users value the low power consumption of operating their CAN transceivers from a 3.3-V supply. However,
some are concerned about the interoperability with 5 V supplied transceivers on the same bus. This report
analyzes this situation to address those concerns.
