Jidis Posted March 28, 2005 Report Share Posted March 28, 2005 I'll try to get some on my next DigiKey order, but I figure they're on something. The PC900 seems to be in every MIDI device I've ever opened, but nothing I feel like destroying. Does anything else use either of those? 4N35 is all over the non-MIDI devices too.-Thanks Quote Link to comment Share on other sites More sharing options...
TK. Posted March 31, 2005 Report Share Posted March 31, 2005 The PC900 is hard to get here in germany (not sure if this is a discontinued product), therefore I decided to use the 6N1386N139 works also, I cannot give a statement for other optocouplersBest Regards, Thorsten.

Jidis Posted March 31, 2005 Author Report Share Posted March 31, 2005 Thorsten, Thanks!They're cheap to order, I just don't have enough of an order built up right now. It seems I bought 6N138's here a while back. Our real electronics store closed down and keeps re-opening under different names in different locations (usually harder to reach each time). If I can figure out where they are for this week, I'll see if they have them.I notice when doing web searches for those part names, 90% of the results came back with MIDI projects. I was hoping they'd be in a bunch of other stuff as well.                    -George Quote Link to comment Share on other sites More sharing options...
stevegs Posted August 17, 2014 Report Share Posted August 17, 2014 Don't use a 6N138/9! They're linear devices. The PC900 isn't really up to much either. The HCPL2200 is much the best! See here: Best Steve G-S Quote Link to comment Share on other sites More sharing options...
