Working Principles

LMV339M/NOPB compares the voltage levels at its input pins and generates digital outputs based on the comparison results. When the voltage at the non-inverting input (Vin+) is higher than the voltage at the inverting input (Vin-), the corresponding output goes high. Conversely, when Vin- is higher than Vin+, the output goes low.
