My newsreader had organised that into a different thread so it was unseen
when I queried the parenthesis portion. Sorry.

I don't know where you got the parenthesised portion of the text from but it
was not in the original post of this thread nor any subsequent one from the
OP.

You still have not said how fast you need to go!
We use H11L1 optos (Schmitt, ~1us, 1.6mA ), as a good trade off between
speed and price.

What is high speed ? 110/9600/115k2/12Mbit/s ?
What isolation requirements 0.5 kV, 2.5 kV, 110 kV or 400 kV ?
>1. Microcoltroller to Microcontroller at TTL Levels.
Standard 20 mA current loop or +/-10 mA bipolar current loop.
>2. RS232
At least RS-232C did not specify speeds above 9k6, so going to 20 mA
current loop would be sufficient.

Hi,
Thanks.
I forgot to add that I need a cheap working solution for mass
production. Something with normal optocouplers.
is it possible.
Thanks,
