Abstract

3.3V Controller Area Network (CAN) transceivers offer advantages and flexibility with respect to 5V CAN transceivers while being compatible and interoperable with each other. Power consumption is lower with 3.3V transceiver compared with 5V transceivers. There is potential for power supply simplification and cost savings when the microprocessor communicating with the transceiver is also at 3.3V. This application note explains these advantages and the devices in TI's CAN transceiver portfolio that can be used for 3.3V CAN systems.
