Disadvantages: - Limited number of comparators (four in total) - Not suitable for high-frequency applications

Working Principles

LMV339M operates based on the principle of voltage comparison. It compares the voltage levels of two input signals and produces a digital output based on the result of the comparison. When the voltage at the non-inverting input is higher than the voltage at the inverting input, the output goes high. Conversely, when the voltage at the inverting input is higher, the output goes low.
