I came across this IC that appears to be a good solution to interfacing Picaxe to I2C bus devices of lower voltage. The device is ADuM1250 and available from RS.

Does anyone have any comment as to its suitability? I am looking at buying one to try between Picaxe and a magnetometer. It is surface mount so might be a bit fiddly to connect.
