I have been pulling my hair out trying to find a datasheet for National Semi part LM1850N. I can find LM1851N which is an 8 pin ground Fault IC and I would venture to guess that my 1850 chip is just another version of that with 14 pins. Can anyone help me on this one? I sell electronic components and would be more than happy to send someone some free NOS or just new stock if they can help me find a datasheet on this one.

George
