ULN2003L Information

Description

The ULN2003L is a Darlington Transistor Array IC from Allegro MicroSystems, specifically designed for high-voltage and high-current applications. This SOIC N-16 packaged device features a 50V voltage rating, 0.5A current capacity, and 1000mW power dissipation. The ULN2003L is suitable for driving inductive loads, such as relays, solenoids, and motors, due to its high gain and low input impedance. It enables the control of up to 8 NPN transistors with a single logic circuit, providing a simple and efficient way to interface digital logic with external devices. In summary, the ULN2003L is a versatile Darlington transistor array IC for driving high-voltage and high-current loads in various applications.

Package

The package type of ULN2003L is SOIC (Small Outline Integrated Circuit) N-16, which means it has a rectangular shape with 16 pins on one side.

Manufacturer
