That's probably the way to go. There are I2C optos, like this IXYS/Clare part: http://www.clare.com/home/pdfs.nsf/www/CPC5902.pdf/$file/CPC5902.pdf But, like the others, it doesn't hold off enough voltage. There are things like the OPI1268 that hold off more voltage, but the Avago part is probably in the sweet spot. - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
