## Description

The LM311 is a single high-speed voltage comparator designed by Motorola Semiconductor. It offers a fast response time of 165 ns, making it suitable for various applications requiring quick signal detection.

This comparator can operate from a wide range of power supply voltages, including single 5-V supplies for logic systems and ±15-V supplies for operational amplifiers. Its output levels are compatible with most TTL and MOS circuits. The device is capable of driving lamps or relays and switching voltages up to 50 V at 50 mA.

Key electrical characteristics include a maximum input bias current of 300 nA and a maximum input offset current of 70 nA. The LM311 also features strobe capability, allowing the output to be held in an off state regardless of the differential input when the strobe is low. All inputs and outputs can be isolated from system ground, and the outputs can drive loads referenced to ground, VCC+, or VCC−.

The LM311 is available in an SOIC package with body dimensions of 6.20 mm x 5.30 mm. This packaging makes it suitable for surface-mount applications.
