I need a simple circuit to convert ADum5241 iCoupler isolator I/O to 3.3 volt levels

I have used the ADum5241 iCoupler before but you need to run it from 5 volts in order to get it to work properly (can't use 3.3 volts).  The IC is nice and small which is great but interfacing it to 3.3 volt logic on the VDD side ends up taking way more PCB area then the isolator does.  I'm currently using 2 SN74LV1T34 level shifters and wonder if any one has any clever ideas that would take up less real estate?
