The LM111 LM211
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. These Comparators
are capable of driving lamps or RELAYs
and switching voltages up to 50 V at 50 mA. All inputs and outputs can be isolated from system ground. The outputs can drive loads referenced to ground, VCC+ or VCC?. Offset balancing and strobe capabilities are available, and the outputs can be wire-OR connected. If the strobe is low, the output is in the off state, regardless of the differential input.
