These devices consist of four independent  
voltage comparators that are designed to operate  
from a single power supply over a wide range of  
voltages. Operation from dual supplies also is  
possible as long as the difference between the two

more positive than the input common-mode  
voltage. Current drain is independent of the  
supply voltage. The outputs can be connected to  
other open-collector outputs to achieve  
wired-AND relationships.

The LM139 and LM139A are characterized for operation over the full military temperature range of  
−55°C to 125°C. The LM239 and LM239A are characterized for operation from −25°C to 125°C. The LM339  
and LM339A are characterized for operation from 0°C to 70°C. The LM2901 is characterized for operation from  
−40°C to 125°C.
