Russell mention to switch the gate with an active method rather than a passive one. So, I thought about a totem pole configuration to carge/discarge the gate. I will use a DS0026 or TC426. How about that now? Thanks for your comments. Dennis. -- http://www.piclist.com#nomail Going offline? Don't AutoReply us! email listserv@mitvma.mit.edu with SET PICList DIGEST in the body
