LM339AN/NOPB TI Comparator | 14-PDIP | Quad, Open Collector, 2V-30V

Product Overview

The LM339AN/NOPB is a quad differential comparator from Texas Instruments, designed for general-purpose applications requiring low power consumption and high accuracy. Housed in a 14-pin PDIP package, it features open-collector outputs that allow wired-AND connections and interface with various logic families. The device operates from a single power supply over a wide voltage range of 2V to 30V (or dual supplies ±1V to ±15V) and offers low input offset voltage (typically 2mV) and low input bias current (25nA). Its versatility makes it suitable for battery-powered systems, industrial controls, and automotive electronics.
