    According to datasheet, other than the comparator count, there's no difference that I could think of.

    The part numbers are different, but I guess that must be self evident.

    The LM393 is a dual comparator, the LM339 is a quad comparator (effectively two 393s in the same package). They share supply pins, and I believe their specs are the same. This is from memory, I recommend looking at the datasheets to be sure.
