I'm in the process of writing a datasheet for an Integrated Circuit, using LaTeX. Anyone knows how to draw a pin configuration diagram, like the one in the attached picture? enter image description here

Here is a solution using tikz. The main feature, I think, is that the pin labels are easy to edit/change. This is possibly fortunate because the labels below are roughly the same as the OPs for pins 1-16 but the remaining labels need to be changed as they just repeat the labels for the first 16 pins.

Here is an image for what my code produces:

and here is the code itself:

  • Thank you very much for your great code example. But I think you forgot \usepackage{amsmath}. – jlk Sep 21 '14 at 20:14
  • I get an Error-Message without amsmath: ! Undefined control sequence. \desc ->V$_{\text {SS}}$ l.28 } – jlk Sep 21 '14 at 21:50
  • @harryhaller Oops, sorry, you are right: it's because of the \text. I'll add it in. Thanks. –  Sep 21 '14 at 21:52

Here is a Circuitiz component version for a general 64 Lead Quad Flat Package. (My OCD seems to be acting up.) Of course, I usually stick components into a separate file where I never have to look at the code again.

  • Holy moly! That's alot of hard-coded stuff. Can you clean the code so TikZ beginners like me have a chance of understanding what's going on? :-) – Svend Tveskæg Sep 21 '14 at 21:31
  • @Svend Tveskæg - I have a tutorial on my web site for a somewhat simpler IC - an 8 pin DIP. http://www.elfsoft2000.com/projects/index.htm – John Kormylo Sep 22 '14 at 03:27
  • Then why use so 'ugly' code here? Some for loops would be nice. – Svend Tveskæg Sep 22 '14 at 03:34
  • LaTeX works by macro expansion. Loops may be prettier, but they save you nothing. – John Kormylo Sep 22 '14 at 03:35
  • Except alot of typing in cases like this. – Svend Tveskæg Sep 22 '14 at 03:42
  • @SvendTveskæg My solution uses loops but this doesn't save much typing. For this question, the most of the "work" is in specifying the labels for the pins (which John doesn't do, so I agree with you that his solution would be simpler if it employed loops). The main advantage of using loops, I think, is that they can make the structure of the code much clearer. In turn, this makes it easier to edit and change the code to make it do something else. –  Sep 22 '14 at 06:13
  • @Andrew My point is that there is a huge amount of code already (338 lines accoring to Emacs) and the labels aren't even written yet. In comparison, your code is 100 lines with all the labels. – Svend Tveskæg Sep 22 '14 at 12:07
  • I should point out that once you type one \savedanchor, \anchor, \pgfpathrectangle and \pgftext you can copy and paste to create the others. After the first 16 you can use replace alls and sign changes. The most typing was done numbering the pins. – John Kormylo Sep 22 '14 at 14:12

You might take a look at

  1. xcircuit and its symbol-libraries (i.e. http://opencircuitdesign.com/xcircuit/)
  2. dia (http://dia-installer.de/shapes/index.html.en)
  3. Circuit_macros https://ece.uwaterloo.ca/~aplevich/Circuit_macros/html/examples.html
  4. circuitikz -> e.g. Display ICs with circuitikz

The first two tools are more like drawing tools but in contrary to others programms they allow you to save the picture as pdf/eps/ps with a .tex-file containing the text.
