Product Summary

The LM111H is a voltage comparator that has input currents nearly a thousand times lower than devices like the LM106 or LM710. The LM111H 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. The inputs and the outputs of the LM111H can be isolated from system ground, and the output can drive loads referred to ground, the positive supply or the negative supply.
