LM239AQDRG4Q1 TI Comparator | 14-SOIC | Low Power, Automotive Grade

Product Overview

The LM239AQDRG4Q1 is a low-power, quad voltage comparator from Texas Instruments, designed for automotive and industrial applications. It operates from a single power supply over a wide voltage range of 2 V to 36 V (or ±1 V to ±18 V for dual supplies). The device features low supply current (0.4 mA per comparator at 5 V), open-collector outputs, and is specified for operation from -40°C to +125°C. Housed in a 14-SOIC package, it is AEC-Q100 qualified for automotive reliability.
