LM311 - High Speed, 30V, Differential Comparator With Strobes

The LM111, LM211, and LM311 devices are single high-speed voltage comparators. Thesedevices are designed to operate from a wide range of power-supply voltages, including ±15-Vsupplies for operational amplifiers and 5-V supplies for logic systems. The output levels arecompatible with most TTL and MOS circuits. These comparators are capable of driving lamps or relaysand switching voltages up to 50 V at 50 mA. All inputs and outputs can be isolated from systemground. The outputs can drive loads referenced to ground, V_CC+ orV_CC−. Offset balancing and strobe capabilities are available, and theoutputs can be wire-OR connected. If the strobe is low, the output is in the off state, regardlessof the differential input.
