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

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.
