LM239AQDREP TI Comparator | 14-SOIC | Low Power, Quad Differential

Product Overview

The LM239AQDREP is a quad differential comparator from Texas Instruments, designed for low-power and high-reliability applications. It operates from a single power supply over a wide voltage range of 2V to 36V (or dual supplies ±1V to ±18V). The device features low supply current (0.4 mA per comparator at 5V) and open-collector outputs that allow wired-AND connections. The LM239AQDREP is specified for the extended industrial temperature range (-40°C to +125°C) and is available in a 14-pin SOIC package. It is a direct replacement for the LM239A and offers enhanced ESD protection and improved performance.
