Аналоговый компаратор, 4 канала, Точность, 4, 1.3 мкс, 2В до 36В, ± 1В до ± 18В, DIP, 14 вывод(-ов).

The LM339N 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.
