Very handy circuit. :o) As far as I can tell this hasn't been addressed before and I expect it will be useful. You mention the possibility of putting some strain on a single o/p pin so why not use two or more in parallel. Don't think I've seen that implemented, but instinctlively I'd use a protective buffer instead -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
