Pinout
The LM2901PT comes in a 14-pin package. Here is a brief description of its pin configuration:
1. Pins 1, 5, 8, 12 - Inverting Inputs for comparators 1 through 4.
2. Pins 2, 6, 9, 13 - Non-inverting Inputs for comparators 1 through 4.
3. Pins 3, 7, 10, 14 - Output Pins for comparators 1 through 4.
4. Pin 11 - Ground (GND).
5. Pin 4 - VCC, the positive power supply.
The LM2901PT operates by comparing the voltages presented at its inverting and non-inverting inputs for each comparator. The output is typically open-collector, providing flexibility for interfacing with other logic levels. It is widely used in applications requiring voltage comparison, such as zero-crossing detectors, level shifters, and oscillators.
