LM239DR.

Аналоговый компаратор, 4 канала, Дифференциальный, 4, 300 мс, 2В до 36В, SOIC, 14 вывод(-ов).

The LM239DR is a Quad Differential Comparator 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 to 36V and VCC is at least 1.5V 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 LM239 device is characterized for operation from -25 to 125°C.
