LP339DR TI Comparator | 14-SOIC | Quad, Low Power, Open Collector Output

Product Overview

The LP339DR from Texas Instruments is a quad low-power voltage comparator designed for applications requiring minimal power consumption and space-saving packaging. Housed in a 14-pin SOIC package, this device features open-collector outputs, making it suitable for driving loads such as LEDs, relays, or logic inputs. With a typical supply current of just 0.4 mA per comparator, the LP339DR is ideal for battery-powered and portable equipment.
