3.3V <-> 5V Document

Hi,

A couple of months ago I saw a PDF document on the Web which described how
to convert 3.3V to 5V (bidirectional). I think it was for I2C applications.
It was a few pages long and I think it used MOSFET's. It may have been a
Philips document. Does anyone know the location of this document? I've
searched in Google with no sucess.

Thanks in advance,
 
care to share the link?

It's okay, I found it.

Sure, here it is:

There is a simpler circuit as well:

If you want another document describing the circuit then take a look at
this:
