Quadruple Differential Comparators

1

DESCRIPTION

The LM339 consists of four independent voltage comparators. These were designed specifically to operate

from a single power supply over a wide range of voltages. Operation from split power supplies is also possible

and the low power supply current drain is independent of the magnitude of the power supply voltage. The

outputs can be connected to other open-collector outputs to achieve wired-AND relationships.
