Pinout
1. Pins 1, 2, 3, 5, 6, 7, 8, 10, 11, 12, 13: These pins are used for the inverting and non-inverting inputs of the four comparators. Each comparator has one inverting (-) and one non-inverting (+) input.
2. Pins 4 and 11: These are the ground (GND) and positive supply voltage (VCC) pins, respectively. Ground is connected to a common reference point, while VCC supplies power to the IC.
3. Pins 1, 2, 3, and 4 (outputs): Each comparator provides an open-collector digital output, which can be connected to other digital logic circuits or used to drive loads based on the comparison result.
In summary, the LM2901M is designed for use in applications that require multiple voltage comparisons, such as in sensor interfacing, analog-to-digital conversion, and threshold detection systems.
