CV Gus Posted February 28, 2009 Share Posted February 28, 2009 I'm looking for schematics for ICs. This includes the 4093, 4081, and 7749 (40 pin). Can anyone help? Thanks. Quote Link to comment Share on other sites More sharing options...

Rybags Posted March 1, 2009 Share Posted March 1, 2009 I keep a couple in my Bookmarks. http://www.datasheetarchive.com/ http://iso-datasheets.com/ Google Search often reaps results. Use Advanced Search, All words, e.g. "74LS138 datasheet" Quote Link to comment Share on other sites More sharing options...

Ian Primus Posted March 4, 2009 Share Posted March 4, 2009 And, then there's the GIICM - a wonderful quick reference for pinouts of parts. -Ian Quote Link to comment Share on other sites More sharing options...
CV Gus Posted March 7, 2009 Author Share Posted March 7, 2009 Thanks again! This is VERY VALUABLE for those of us trying to repair this stuff- it's fine for a schematic to show a "(####)" chip, but you can't test it if you don't know what it's supposed to be doing. This is what made the schematic for the CV Roller Controller so nifty; it DID tell you. Quote Link to comment Share on other sites More sharing options...
