The LM311 device is a single high-speed voltage comparator. This device is 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.

It is 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.

Features:

• Fast Response Time: 165 ns
• Strobe Capability
• Maximum Input Bias Current: 300 nA
• Maximum Input Offset Current: 70 nA
