These devices consist of four 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 wire-AND relationships.
The LM139 and LM139A are characterized for operation over the full military temperature range of –55 deg C to 125 deg C. The LM239 and LM239A are characterized for operation from –25 deg C to 125 deg C. The LM339 and LM339A are characterized for operation from 0 deg C to 70 deg C. The LM2901 is characterized for operation from –40 deg C to 125 deg C.
