Depending on setting the reference voltage and the hysteresis, the lower threshold voltage of the hysteresis may become the negative voltage.
I show a concrete example below.
My customer uses a circuit such as the above.
In this case, the hysteresis voltage is about 80mV, therefore -VH/2 is -10mV(=30mV - 80mV/2).
So my question is,
If the input is less than -10mV, does the output become the high level?
