description/ordering information
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, V
CC+
or V
CC–
.
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.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
