Differential Comparator With Strobes - LM311

LM311 (ACTIVE)

Differential Comparator With Strobes

Recommended alternative parts

  • LM393  -  Dual differential comparator
  • LMV393  -  Dual general purpose low voltage comparator
  • LMV331  -  Single low voltage comparator
  • LM339  -  Quad differential comparator
  • LM306  -  Single, Strobed, High Speed Differential Comparator with Push-Pull Outputs

Description

The LM111, LM211, and LM311 devices 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.
