LM2903VQDR

The LM2903VQDR is a quad comparator from Texas Instruments. It is a monolithic integrated circuit that consists of four independent voltage comparators, each with an open-collector output stage. The LM2903VQDR is designed for a wide range of applications, including signal processing, voltage level detection, and pulse generation.

Description:

The LM2903VQDR is a 14-pin quad comparator that operates from a single supply voltage ranging from 3V to 32V. It features a quiescent current of 1.8mA per comparator and an input current of ±2µA. The comparators have a propagation delay of 8ns and a maximum output current of ±200mA.
