TILM339N/NOPB
Overview
The LM339N/NOPB is a versatile quad differential comparator designed to operate from a single power supply over a wide voltage range of 2V to 36V. It features four independent comparators with open-collector outputs, allowing for easy interfacing with various logic levels and wired-OR connections. The device is specifically designed to sense signals near ground level, even when powered by a single supply.
Why Choose This Part
The LM339N/NOPB offers high flexibility with a wide input common-mode range that includes ground, eliminating the need for dual power supplies in most applications. Its open-collector outputs allow for easy logic integration, while the low quiescent current of approximately 0.8mA makes it suitable for power-sensitive designs.
Applications
Key Specifications
Getting Started
To use this part, place it on a breadboard or PCB and provide a supply voltage between 2V and 36V between pins 3 (V+) and 12 (GND). Because the outputs are open-collector, you must connect a pull-up resistor from the output pin to your desired logic voltage (e.g., 3.3V or 5V) to observe a high signal state. Ensure the input voltages do not exceed the supply voltage to maintain proper operation.
