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 will be in the off state regardless of the differential input. The LM111 is characterized for operation over the full military range of – 55°C to 125°C. The LM211 is characterized for operation from – 40°C to 85°C, and the LM311 is characterized for operation from 0°C to 70°C. LM111 . . . JG PACKAGE LM211, LM311 . . .
