justifying use of this component beyond specified  
performance and environmental limits.  
DESCRIPTION/ORDERING INFORMATION  
This device 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 2 V to 36 V, and VCC is at least 1.5 V 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 LM293-EP is characterized for operation from –55°C to 125°C.
