Fairchild do a tiny logic series of surface mount buffers that have 5v
tolerant inputs whwn running on lower voltages.
Try the NC7SZ125 for example.

Subject: [EE]: "5V tolerant" 3V buffer?


I need to convert a couple 5V logic lines out of a PIC running on 5V to
3V levels to drive a MultiMedia card. I've seen some 3V PLDs that have
"5V tolerant" inputs. Does anyone know of a simple buffer like that? One
that I'd be able to power with my 3V supply, but drive the inputs with
0V and 5V?

Thanks!

Harold
