6N138N chip in the US/Canada

[xploited]

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.

Are any of these the correct ones? or possible can someone in north america tell me where they got theres!

thanks

Yes, 6N138 is right.
