LM339MX TI Comparator | 14-SOIC | Quad, Low Power, 2V to 36V

Product Overview

The LM339MX from Texas Instruments is a quad differential comparator designed for low-power, low-voltage 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 drain (0.8 mA typical) independent of the supply voltage. The device has open-collector outputs that can be connected to other open-collector outputs to achieve wired-AND relationships. The LM339MX is offered in a 14-pin SOIC package, making it suitable for space-constrained designs.
