I don't want to spend $5-8 per relay, because I'll nee= d 3 or 4 relays. And size - DIP is kinda big. I would prefer SOT23 type, but not the biggest issue. I can get more than adequate SOT23 N channel MOSFETs for a few cents, so if I can make an SSR out of those, it would be idea. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
