LM339M/NOPB TI Comparator | 14-SOIC | Quad, Low Power, Open Collector

Product Overview

The LM339M/NOPB is a quad differential comparator from Texas Instruments, designed for low-power, high-precision voltage comparison in a compact 14-SOIC package. It features open-collector outputs, wide supply voltage range (2V to 36V), and low supply current (0.8 mA typical). This device is ideal for battery-powered systems, industrial controls, and automotive electronics.
