When the input voltage rises above 4 V, the output switches to 5 V (logic HIGH). When the input voltage falls below the lower hysteresis threshold (slightly below 4 V), the output switches back to 0 V (logic LOW). This hysteresis prevents rapid toggling due to noise or small fluctuations near the threshold.
- Use Cases:
- Signal conditioning for sensors with analog outputs
- Waveform shaping for slow or noisy signals
- Level detection and threshold monitoring in control systems
- Interface between analog sensors and digital microcontrollers or PLCs
