## Description
The LM393B/LM2903B are next-generation versions of the industry-standard LM393/LM2903 comparators, offering improved performance for cost-sensitive applications. These devices consist of two independent voltage comparators designed to operate from a single power supply with a wide voltage range. Quiescent current is independent of supply voltage, and outputs can be wired-AND for certain configurations.
