TILM339AN
Overview
The LM339AN is a quad general-purpose differential comparator designed to operate from a single power supply over a wide range of voltages from 2V to 30V. It features four independent voltage comparators in a 14-pin PDIP package, each with an open-collector output that allows for easy interfacing with various logic families. This component is a staple for analog signal processing where multiple threshold detections are required in a single footprint.
Why Choose This Part
The quad-channel configuration provides high functional density for complex monitoring circuits while maintaining low power consumption with a maximum quiescent current of 2.5mA. Its 14-PDIP through-hole package makes it ideal for rapid prototyping, breadboarding, and easy manual assembly in industrial or hobbyist environments.
Applications
Key Specifications
Getting Started
To use the LM339AN, ensure the open-collector outputs are connected to a pull-up resistor to the desired logic voltage level. Since it is a through-hole component, it can be directly inserted into a standard solderless breadboard for testing or mounted in a 14-pin DIP socket for easy replacement. For high-speed applications, keep input traces short to prevent oscillation, and always bypass the VCC pin with a 0.1uF ceramic capacitor to ground.
