[WriteLog] possible substitute for dual opto-isolators

[W. Wright, W5XD]

Browsing the Digikey catalog, I see the following parts:

TLP621-2-ND
TLP624-2-ND		---appears to be in stock at Digikey
PS2505-2NEC-ND	---I have used this one. It has dual LED's that are not used,
but don't hurt
PS2506-2NEC-ND	--I have used this one. Darlington outputs work fine, too.

Any of these should work, although I have only tried the one I note.

Wayne
