I2C Level Shifting

James Long

Ok...so I'm using I2C but I need to level shift the voltage on the bus.

Does anyone have a surface mount enhanced channel part they use for this??

I want to make sure I use the correct part ....to prevent problems.

Thanks,

James Long

There's a whole thread on this (including I2C): http://forums.parallax.com/forums/default.aspx?f=25&m=124837

James -

If that thread doesn't get you what you need (I didn't check it) Philips Semiconductor has b-directional (necessary!) I2C level shifters. Shout if you need a link to them.
