what is the difference between LM393 and LM339?
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.
LM54? need more characters
