Working Principles

The MAX6380XR43-T operates by comparing the input voltage with the threshold voltage set by the user. When the input voltage exceeds the threshold, the digital output goes high, indicating a "high" state. Conversely, when the input voltage falls below the threshold, the digital output goes low, indicating a "low" state. The threshold voltage can be adjusted using an external resistor divider connected to the TH pin.
