If you are after a solution for a level shifter here is an interresting Application Note from PHILIPS
AN97055 (http://www.semiconductors.philips.com/acrobat_download/applicationnotes/AN97055.pdf)

With SOT23 FETs and 805 (or 1206) Resistors it takes minimal PCB space.

Or you could use one of these... I use them all the time. They make a 4 channel and an 8 channel version.

Oops, I can't upload the data sheet, It's too big. The part number is TSX0102 for the 2 channel one and TSX0104 for the 4 channel one. They are made by Texas Instruments. Try it, Youl'l like it...
