With four independent comparators operating from 2-30V, open-collector outputs, and input range including ground, it is the most widely used comparator for voltage monitoring, level detection, and threshold comparison.","working_principle":"Each comparator consists of a differential input pair and an open-collector NPN output. When the non-inverting input exceeds the inverting input, the output transistor turns off (high impedance), requiring an external pull-up resistor. The wide supply range and ground-inclusive input range make it extremely versatile for analog-to-digital interface applications.","pin_description":"
