I'm using the LM339 for an application with different voltage ranges. I am using the window comparator circuit since I want to test a specific range (4 - 8V). The circuit shown below actually identifies this "window" but not as I am expecting. When the input value is in this window I want to light the led, instead the led is off. Is there a way I could invert this output to light it in the window and turn it off when it's out of range?
Sorry if it's too dumb, but I'm stuck with this.
