integrated circuit - -5/0 volt to 0/5 volt logic levels?

Does anyone know a good way to convert -5/0 volt logic to 0/5 volt? I'm using a chip as seen in the diagram below, but I'm not sure what to do about the inverted logic levels. Basically, I need to add 5 volts to both logic levels to fix it (-5 volt goes to 0, 0 volts goes to 5). I know I can do the level shifting with some MOSFETs, but I'm space limited on the board so it would be really helpful if anyone could recommend an IC to do the conversion. If there is no such IC, what would be the best discrete circuit to do the conversion?

Thanks.
