LM393 datasheet

 

Description :

The LM393 consist of two independent voltage comparators that is 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 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 LM2903 is characterized for operation from −40°C to 125°C.
