If the pulse has just happened to go high and your gate makes it low, that is a narrow pulse and you will have in effect just given it a clock signal much higher than it is rated for. That could crash it. Barry -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
