Other Parts Discussed in Thread: SN65HVD233, SN65HVDA542-Q1

HI

Can i check for your kind opinion?

Is SN65HVD233 able to support 

  • SAE J2284 High-Speed CAN for Automotive Applications

Where this specification is defining the Physical Layer and portions of the Data Link Layer of the ISO model for a 500 KBPS High-Speed CAN (HSC) protocol implementation.

Support for SAE J2284 is not mentioned in the data sheet of SN65HVD233 as compared to SN65HVDA542-Q1 where it is clearly defined.

  • Hi Ivan,

    The SN65HVD233 is a 3.3V CAN transceiver designed for industrial applications such as building automation and robotics.

    The SN65HVDA542-Q1 is a different core device and was designed with automotive applications in mind. You are not comparing apples to apples by comparing these two devices. The J2284 standard is an automotive standard and should not be confused with industrial applications.

    Why do you need a 3.3V automotive qualified CAN transceiver? Is it to interface with a 3.3V micro controller on your bus? For this type of application, a device like the SN65HVDA542-Q1 makes the most sense. It is a 5V CAN transceiver with selectable output voltages on the RXD pin which is the input to the uC. This way the input voltage requirements of the uC are not violated, which could potentially damaging the device, but the bus side voltage requirements for automotive CAN are still maintained via the 5V supply.
