Quad Differential Comparator

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 wired-AND relationships. The LM139 and LM139A are characterized for operation over the full military temperature range of -55C to 125C. The LM239 and LM239A are characterized for operation from -25C to 125C. The LM339 and LM339A are characterized for operation from 0C to 70C. The LM2901 LM2901AV and LM2901V are characterized for operation from -40C to 125C. By Texas Instruments
