IC Diagrams.

[CV Gus]

I'm looking for schematics for ICs. This includes the 4093, 4081, and 7749 (40 pin).

 

Can anyone help?

 

Thanks.

Google Search often reaps results. Use Advanced Search, All words, e.g. "74LS138 datasheet"

Now that's something!

 

Thanks a plenty!

And, then there's the GIICM - a wonderful quick reference for pinouts of parts.

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.

Another site is http://www.alldatasheet.com/ , which almost has all datasheets.
