In the process of developing an RDM Compatible DMX receiver board (using a ATMEGA328) and I have been fortunate enough to come across kimliv's most informative answer concerning such a board;

DMX on Arduino with RS485DMX on Arduino with RS485

However I was wondering why (if) it is necessary to use a TTL Compatible isolator? In this case the 6N317 or if perhaps a more traditional repeater isolator style circuit could be implemented using a more common and cheaper isolator for example the H11A1 (which I just so happen to have in stock).

This all said it seems several DMX circuits I have come across utilise the 6N317 but so far as I am aware the transceiver (MAX481) could be used to drive other isolators.

Is there something obvious I am missing here? or anything in particular that makes the 6N317 quite so desirable for its use here?

thank you.

choosing the right Opto isolator?
