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
