Default Need comparator recommendation

Hello -

I've been using the LM339 comparator in a few different places and like it very much. It is cheap, stable, easy to use, and has 4 comparators in one package.

Now I need to find a comparator that handles +/-12 on the input stage, but the output voltage swing is from ground to +5. I've found a couple of possible candidates, but an wondering if you all have any favorites to recommend. A quad would be nice....

Thanks,
Charles Hansen

Why not just limit output swing with a zener + resistor (or use a transistor switch)?

Sheer laziness. I figure that there are comparators with level translators built in, so that I don't have to....
