LP339M/NOPB TI Comparator | 14-SOIC | Quad, Low Power, Open Collector

Product Overview

The LP339M/NOPB is a quad low-power, low-offset voltage comparator from Texas Instruments. It is designed for applications requiring low power consumption and high accuracy. The device features open-collector outputs, making it suitable for wired-OR configurations and interfacing with various logic families. Housed in a 14-pin SOIC package, the LP339M/NOPB operates over a wide supply voltage range from 2V to 36V (or ±1V to ±18V). Its low supply current of 0.8mA per comparator at 5V makes it ideal for battery-powered and portable equipment.
