Product Summary

The LM139AD is an independent voltage comparator 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; (2)wired-AND relationships. The LM139AD is characterized for operation over the full military temperature range of -55℃ to 125℃.
