Product Summary

The LM311M is a voltage comparator that has input currents nearly a thousand times lower than devices like the LM106 or LM710. The LM311M 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, the LM311M can drive lamps or relays, switching voltages up to 50V at currents as high as 50 mA. Both the inputs and the outputs of the LM311M can be isolated from system ground, and the output can drive loads referred to ground, the positive supply or the negative supply.
