LM2903P-MAND TI Comparator | Dual, Low Power | 2-36V Supply, Open Collector Output

Product Overview

The LM2903P-MAND from Texas Instruments is a dual low-power voltage comparator designed for industrial and automotive applications. It operates from a single power supply over a wide voltage range of 2V to 36V (or ±1V to ±18V for dual supplies) and features low supply current drain (0.4 mA per comparator at 5V). The device has open-collector outputs that can be connected to achieve wired-AND logic. It is available in a PDIP-8 package and is characterized for operation from -40°C to +125°C.
