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

can be wire-OR connected. If the strobe is low, the  
output will be in the off state regardless of the

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.
