0 General Description
The LM111, LM211 and LM311 are
voltage comparators that have input currents nearly a thousand times lower than devices like the LM106 or LM710.
They are 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.
Their output is compatible with RTL, DTL and TTL as well as MOS circuits.
Further, they 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 LM111, LM211 or the LM311 can be isolated from system ground, and the output ...
