description/ordering information  
This device consists 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 is possible, as long as the difference  
between the two supplies is 2 V to 36 V, and V  
is at least 1.5 V more positive than the input common-mode  
CC  
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 LM2903Q is tested from −40°C to 125°C and is manufactured to demanding automotive requirements.
