Lifting "a pin" often causes it to break off. May as well pull the part for later reuse.
Agree on the inversion issue. One needs to be careful as 3.3V CMOS logic is usually not (or "not exactly") TTL compatible. Crossing power supply boundaries means having to assure the associated pins are not unhappy - i.e. drawing excess current - when either supply is missing. ________________________________ From: "li...@lazygranch.com" <li...@lazygranch.com> To: Discussion of precise time and frequency measurement <time-nuts@febo.com> Sent: Thu, July 28, 2011 1:39:06 PM Subject: Re: [time-nuts] Electronics Question Technically, he just has to lift the offending pins. My recollection is the transmitters invert, so that might be an issue. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
