LM339LVPWR TI Comparator | 14-TSSOP | Low Power, Open Collector Output

Product Overview

The LM339LVPWR from Texas Instruments is a low-power, low-voltage quad comparator designed for applications requiring precision voltage comparison with minimal power consumption. It operates from a single supply voltage as low as 2.0V up to 5.5V, making it ideal for battery-powered and portable devices. The device features open-collector outputs that can be pulled up to any voltage up to 5.5V, independent of the supply voltage, enabling easy interfacing with various logic families. With a typical supply current of just 100 µA per comparator, the LM339LVPWR significantly extends battery life in portable applications. It is offered in a compact 14-TSSOP package, suitable for space-constrained designs.
