LM311 Description

Short technical summary and product information.

The LM311 is a single high-speed voltage comparator designed for versatile operation across various power supply voltages, including ±15V and 5V logic systems. Its output levels are compatible with most TTL and MOS circuits, enabling it to drive lamps or relays and switch voltages up to 50V at 50mA.

 

Key electrical characteristics include a fast response time of 165 ns, a maximum input bias current of 300 nA, and a maximum input offset current of 70 nA. The device offers strobe capability, allowing the output to be forced into an off state. All inputs and outputs can be isolated from system ground, and the outputs can drive loads referenced to ground, VCC+, or VCC−.

 

This comparator is available in an SOIC (8) package with a body size of 4.90mm x 3.91mm. Its design makes it suitable for applications such as desktop PCs, body control modules, white goods, building automation, oscillators, and peak detectors.
