SN65HVD72: Inquiry about schematic review

Part Number: SN65HVD72
Other Parts Discussed in Thread: THVD1419, THVD1410


I need schematic review and double check for me.

Below is our customer's schematic.

Could you please let me know your comment?

Best Regards,


  • Michael,

    The SN65HVD72 has integrated failsafe, so there is no need for external failsafe biasing resistors just for that device alone. This is described in detail in the SN65HVD72 datasheet section Receiver Failsafe. I am referring to R42 and R43 in your schematic. If these are needed for other devices on the bus, then that's fine.

    Other than that, I see no major concerns in the schematic, provided this view of it.

    I would recommend also considering the THVD1410 or the THVD1419, which are pin-to-pin replacements that offer better common voltage range and improved ESD/EFT behavior.



  • Hi Danny,

    Thanks a million.

    Best Regards,
