The English datasheet is here:

This PDF shows a circuit for using these in a MIDI interface:

Hello Andy,
I am not able to click the second link of the circuit tutorial, do you mind check it again 😀 Thanks!

Hi Chao,
The link works for me, but maybe the %20 (spaces) are a problem in some browsers?
Instead. start here:
ftp://downloads.polaraudio.co.uk/Technical/CUE
Then click “Application Notes”
followed by “Control of MIDI Device by CUE Control System”
then click on “Control of MIDI Device by CUE Control System.pdf”

There’s a slightly better circuit diagram of a MIDI interface using an opto isolator/coupler like these at the bottom of this page:
http://www.gmarts.org/index.php?go=322
That shows a PC parallel port MIDI interface (software controlled), with 220 Ohm resistors in the MIDI out circuits to protect against shorted outputs.
That site has some very good information about the MIDI protocol too.

Simple, cheap yet reliable optocoupler. PC817 is my favorite optocoupler for most of my projects, especially when working with relay and inductive driving.
