• Fast Response Times • Strobe Capability • Maximum Input Bias Current.。。 300 nA • Maximum Input Offset Current 。 。 。 70 nA • Can Operate From Single 5-V Supply • Designed to Be Interchangeable With National Semiconductor LM111， LM211， and LM311 description The LM111， LM211， and LM311 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 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.
