What are the key features of LM339N-P2?
- Four independent comparators in a single 14-pin DIP package reduce board space and component count
- Open-collector outputs support wired-OR configurations and flexible logic-level interfacing from 2 V to 36 V
- Wide supply voltage range of 2 V to 36 V single-supply enables use across 3.3 V, 5 V, and 12 V systems
What is LM339N-P2 used for?
The LM339N-P2 is widely used in window comparator circuits, zero-crossing detectors, and level-shifting applications across consumer electronics, industrial control systems, and automotive accessories. Its open-collector outputs allow direct interfacing with TTL and CMOS logic without additional level-translation components. The quad channel configuration in a through-hole DIP package makes it a cost-effective solution for prototyping and education platforms.

Frequently Asked Questions
What supply voltage range does LM339N-P2 support, and how flexible is it across common logic levels?
LM339N-P2 operates on a single supply from 2 V to 36 V or a dual supply of ±1 V to ±18 V, covering 3.3 V, 5 V, 12 V, and 15 V systems without circuit modifications. This wide range allows the same device to be used across microcontroller interfaces, op-amp-powered circuits, and automotive 12 V environments.
How do the open-collector outputs of LM339N-P2 simplify multi-comparator wired-OR logic designs?
The open-collector outputs allow multiple LM339N-P2 comparator outputs to be tied together on a single pull-up resistor to implement a wired-OR function with no additional logic gates. This is particularly useful in fault-detection circuits where any of 4 input threshold violations should drive a single alarm line low, reducing gate count and PCB routing complexity.
When is LM339N-P2 preferred over the LM393 dual comparator for a new PCB design?
LM339N-P2 is preferred when 4 independent comparison channels are needed in a single 14-pin DIP package, saving roughly 30 mm² of board area compared to two LM393 packages, and reducing assembly cost by consolidating 4 comparators into 1 BOM line. It is especially advantageous in through-hole prototyping or educational applications where breadboard-friendly DIP packaging is required.
