Product Summary

The LM111, LM211, and LM311 are single high-speed voltage comparators. These devices are designed to operate from a wide

 range of power-supply voltages, including ±15-V supplies for operational amplifiers and 5-V supplies for logic systems. The 

output levels are compatible with most TTL and MOS circuits.
