Your problem is that you can't get the tlp557 optoisolator parts?
That's too bad, they're nice parts, well suited for various special
applications. Hmm, DigiKey has 743 of them in stock, at $1.80 each.

Digikey has the TLP557:
http://rocky.digikey.com/scripts/ProductInfo.dll?Site=US&V=264&M=TLP557

It costs $1.80 if you buy just one or $14.40 for ten of them. They have
628 in stock so I guess there is no hurry.
