LP239D TI Comparator | Low Power, Open Collector Output, 2V to 30V

Product Overview

The LP239D from Texas Instruments is a low-power, quad-channel comparator designed for general-purpose applications. It operates from a single power supply over a wide voltage range of 2V to 30V (or ±1V to ±15V dual supplies) and features low supply current (0.4 mA per comparator typical). The open-collector output allows wired-OR connections and interfacing with various logic families. The LP239D is available in a 14-pin SOIC package, offering space-saving benefits for compact designs.
