The LM339N is a low-power quad voltage comparator IC designed to operate from a single power supply or dual supplies. Each comparator in the package functions independently and compares two voltages to output a digital high or low signal.
It is ideal for analog-to-digital conversion, zero-crossing detectors, voltage monitoring, and general purpose comparator applications in both hobbyist and industrial-grade electronics.
The N suffix indicates it's in a standard DIP-14 through-hole package, making it easy to use on breadboards and prototyping boards.
