Product Summary

The LM311CH is a voltage comparator. The LM311CH has input currents nearly a thousand times lower than devices like the The LM311CH. The LM311CH is also designed to operate over a wider range of supply voltages: from standard ±15V op amp supplies down to the single 5V supply used for IC logic. Its output is compatible with RTL, DTL and TTL as well as MOS circuits. Further, it can drive lamps or relays, switching voltages up to 50V at currents as high as 50 mA.
