After a long search (most of my day) of both RS and farnell, which I will continue, can anyone reccomend, a single or dual (or more) channel driver, that will source or sink 30mA (each channel) @ 24V, compatible with 3.3V I/O (mbed). I'm either being very dim here or rs have very few devices which go above 18V, and none are 3.3 CMOS compatible, and farnell has given me a small headache.
I'm not bothered whether they are low or high side drivers, I can attach the load i am driving in either arrangement. I do hope someone has a chip in their arsenal suitable. OR someone points out an obvious shortcoming in my searching.
Regards.
EDIT: for example

gives me 'cmos compatible' but I am unsure of whether using an mbed pin will be damaged by this device or not?
