ONSEMI LM311DR2G Voltage Comparator

The LM311 is a versatile, single comparator capable of operating from a 5.0 V to 30 V single power supply or split supplies up to +15 V. It features inputs isolatable from ground, high output current drive to 50 mA, and voltage switch capabilities up to 50 V. Suitable for relay, lamp, or solenoid driving, it offers high speed response, low offset voltage, and low power dissipation. Its design supports applications in noise filtering, switching, and level detection, making it essential for industrial, automation, and sensing systems.
