$5000TI LM139AW
Comparator General Purpose Open-Collector, Open-Drain 14-CFP
LM139AW 概要
The LM139A-MIL device consists 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 LM139A-MIL device is characterized for operation over the full military temperature range of –55°C to +125°C.
