Protection circuits

Hi everybody, after a lot of google-research looking for practical information about ho to protect integrated circuits from external world, i have thrown in th towel.

Does anyone have suggestions? In particular, I want to protect a video processor (SAA7113) from signal coming from a RCA connector (composite video), just in case somebody make a wrong connection. I think it is a ESD related stuff.

Thanks in advance!! Joe

Although these device add a significant capacative load which your circuit may not be able to tolerate. The easiest method is often series resistors.

First of all aquaint yourself with my series oif articles, "Reading the World" and Writing the World". This series of four articles deals with real world interface problems in general. You can find them at:

The main trick is to think about limiting unwanted energy.
