Hi,

Can I design with a part like the SN65HVD379 one connection that can support the RS485 and RS422 protocols?

thanks,

     The device is a RS485/422 compatible driver / receiver chip. I don't understand your question?

    Can you be more specific please?

    Hi Thomas,

    I dont know yet which protocol I will use, 485 or 422.

    How can I have one IC for both protocols?

     

    thank you for your answer.

    these are no protocol standard but electrical standards only. Because RS485 is a little stronger than RS422, this device can deal with both.

    regards, Thomas
