LM239PW TI Comparator | 14-TSSOP | Low Power, Quad Channel

Product Overview

The LM239PW from Texas Instruments is a quad-channel, low-power voltage comparator designed for industrial and automotive applications. It operates from a single power supply over a wide voltage range of 2V to 36V (or dual supplies ±1V to ±18V) and features low supply current (0.4 mA per comparator at 5V). The open-collector outputs allow wired-AND connections, making it suitable for level detection, window comparators, and oscillator circuits. Housed in a 14-pin TSSOP package, it offers a compact solution for space-constrained designs.
