1) I have an LM139 comparitor supplied with +15 Volts and Ground. The - input is at + 2 Volts. There is no hysterisis. If the + Input opens will the output pin with a 6K Pull up Resistor to +15 Volts be high or low.
2) I have a second case. The + Input is biased to +10 volts and the - pin opens. What is the state of the output.
Please e-mail aeroneer@aol.com or call me at 201-240-4671
I appreciate your help.
