I used to have a seven or eight page compressed listing of the 74 and 4000 series chips with their pinouts but I’ve misplaced it. Does anyone have this that they could scan in or perhaps a URL where they could be found (failed to find it on a websearch). Are there any reference CD’s with search facilities out there for general electronic parts??

 

There’s a really useful resource called “The Hardware Book” at http://www.hwb.acc.umu.se which is full of all sorts of pinouts including (I think!?) the 4000 and 74 series. You can download the site too which is handy for off line referencing. Geoff Moore Straight Forward Solutions Ltd Maynooth Road, Prosperous Co.Kildare, Ireland +353(0)45892739 [email protected]
