Working Principles

LM2901PW compares the voltages applied to its input pins and generates digital outputs based on the comparison results. It uses internal reference voltages to determine the threshold for 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 non-inverting input is lower, the output goes low.
