LM139 Differential Comparator: Circuit, Pinout and Datasheet PDF

The LM139 device consists of four independent voltage comparators that are designed to operate from a single power supply over and 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 LM139 device is characterized for operation over the full military temperature range of –55°C to 125°C.
