description/ordering information  
These devices consist of two 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 supplies is  
NC − No internal connection  
2 V to 36 V, and V  
is at least 1.5 V more positive than the input common-mode voltage. Current drain is  
CC  
independent of the supply voltage. The outputs can be connected to other open-collector outputs to achieve  
wired-AND relationships.  
The LM193 is characterized for operation from −55°C to 125°C. The LM293 and LM293A are characterized for  
operation from −25°C to 85°C. The LM393 and LM393A are characterized for operation from 0°C to 70°C. The  
LM2903 is characterized for operation from −40°C to 125°C.  
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.
