LM339 Low Power Low Offset Voltage Quad Comparator IC DIP-14 Package (Pack Of 5)

Description

1. IC Type: LM339 is a quad comparator IC, meaning it contains four separate comparator units within a single IC package.
2. Comparator Function: Comparators are used to compare two voltage inputs and provide a digital output based on the comparison result. The LM339 has four independent comparator channels.
3. Low Power: It is designed for low power consumption, making it suitable for battery-operated or low-power applications.
4. Low Offset Voltage: The LM339 is known for its low offset voltage, which means that the input voltages do not need to be very close to each other for the comparator to provide accurate comparisons.
5. DIP-14 Package: The IC comes in a DIP-14 package, which is a through-hole package style and can be easily mounted on a standard PCB.
6. Input Pins: Each comparator typically has two input pins, one for the non-inverting input (+) and the other for the inverting input (-).
7. Output Pins: For each comparator, there is one output pin that provides a digital logic level (high or low) based on the comparison result.
8. Open-Collector Outputs: The outputs of the LM339 are often open-collector outputs, which means they can be connected to external pull-up resistors to interface with other digital or microcontroller circuitry.
9. Hysteresis: Some versions of the LM339 may include hysteresis to prevent output oscillation near the threshold voltage.
10. Applications: The LM339 is widely used in applications such as voltage monitoring, window comparators, signal conditioning, and control systems where voltage comparison is necessary.
11. Voltage Compatibility: Always check the voltage compatibility of the LM339 with your specific application, as it might vary depending on the version or manufacturer.
12. Datasheet: For precise details regarding electrical characteristics, pin configuration, and usage, it’s essential to refer to the datasheet provided by the manufacturer.
