The LM393ST is a dual voltage comparator with a total of 8 pins. Here is a brief overview of its pin configuration and functions:
1. VCC (Pin 8): This is the power supply pin for the IC. It provides the necessary voltage for the comparator to operate.
2. GND (Pin 4): This is the ground pin and is connected to the 0V reference of the power supply.
3. Non-Inverting Inputs (Pins 3 and 5): These are the input pins for the non-inverting terminals of the two comparators within the IC. The voltage applied here is compared with the voltage at the inverting input.
4. Inverting Inputs (Pins 2 and 6): These are the input pins for the inverting terminals. The comparator compares this voltage with the voltage at the non-inverting input.
5. Output (Pins 1 and 7): These are the output pins for the two comparators. The output is typically an open-collector output, which means it can be pulled high externally.
The LM393ST is commonly used in applications where voltage comparison is needed, such as in zero-crossing detectors and voltage level monitoring.
