If it did, it wouldn't be 10V. 10V is way above the absolute maximum rating for those inputs, so you should expect it to cause serious damage. > Will it allow a current to flow or will it still be high impedance? Probably lots of current for a short time. No guarantees after that. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
