LM239DRG3 TI Comparator | 14-SOIC | Low Power, Open Collector Output

Product Overview

The LM239DRG3 is a low-power, quad voltage comparator from Texas Instruments, designed for applications requiring precision voltage comparison with minimal power consumption. Housed in a compact 14-SOIC package, it features open-collector outputs that allow for wired-AND connections and flexible interfacing with various logic families. The device operates from a single power supply over a wide voltage range of 2V to 36V (or ±1V to ±18V for dual supplies), making it suitable for both battery-powered and industrial systems. Its low supply current of 0.4mA per comparator at 5V ensures energy efficiency, while the input common-mode voltage range includes ground, enabling single-supply operation. The LM239DRG3 is a direct replacement for the industry-standard LM239 and is characterized for operation from -40°C to +125°C, ensuring reliability in harsh environments.
