Hey,
Working on building this drum module you've made but I'm having trouble sourcing out one of the components. I've managed to find everything else except the 6N138N.
is http://www.fairchildsemi.com/pf/6N/6N138.html the proper chip? (heres a link directly to the datasheet http://www.fairchildsemi.com/ds/6N/6N138.pdf
They don't mention the 6n138n so I'm really not sure if its the same. I can't find a data sheet on it either, the 6n138 I can, but not the 6n138n.
Are there any alternatives to this chip?
Here are 3 I found on mouser that I'm not sure if they are the right ones.
