SN65HVD72: what is the possible cable length of SN65HVD72DGKR ?

Danny,

It's a good question, which applies to the general RS-485 transceivers. What's the data rate of your application and cable length? You can check out #5 in this FAQ for the discussion.

TI also has published some bench data with THVD1550.

BTW, if you're interested, TI has recently released many new RS-485 transceivers. You can find the summary here.

Please let me know if you have more questions.
