Schmitt triggers help prevent a wavering signal voltage from causing a rapid repeated high/low triggering near a single voltage. It has 2 threshold voltages and a middle ground voltage called hysteresis that needs to be exceeded in order for the output to change.
- When + input voltage is high enough above – input, then the output will be high.
- If + input voltage is low enough below – input, then the output is low.
- There is a middle ground voltage (hysteresis) where the output is either high or low based on what the output was last put into.
