LM239J TI Comparator | 14-CDIP | Quad, Low Power, Open Collector

Product Overview

The LM239J from Texas Instruments is a quad differential comparator designed for industrial and military-grade applications. Housed in a 14-pin ceramic dual-in-line package (CDIP), it offers low power consumption and wide supply voltage range. The open-collector outputs allow wired-AND connections, making it ideal for level detection, logic interfacing, and signal conditioning in harsh environments.
