Hi all, I have a comparator LM339M, what is its main purpose ? It has 4 inputs and 4 outputs as well as a Vcc and ground connection. When do the outputs go high ? Can you explain the basics. I do'nt have a specific purpose intended for it, I just want to know when outputs 1-4 go high or low and when and why..... Thanks in advance.... Jim
