LM2903BYST ST Comparator | 8-MINISO | Dual, Low Power, 2V-36V

Product Overview

The LM2903BYST is a dual low-power voltage comparator manufactured by STMicroelectronics. It is designed to operate from a single power supply over a wide range of voltages (2V to 36V) or from dual supplies (±1V to ±18V). The device features low supply current (0.4mA per comparator at 5V) and open-collector outputs that allow wired-AND connections. The LM2903BYST is housed in the 8-MINISO package, which is a miniature small outline package suitable for space-constrained applications.
