LM393
Description
The LM393 consists of two 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.
