ULN2001A Description

Short technical summary and product information.

The ULN2001A is a high-voltage, high-current Darlington Array manufactured by Motorola Semiconductor. It contains seven open collector Darlington pairs with common emitters, each channel rated at 500 mA and capable of withstanding peak currents of 600 mA. The device features an output voltage of 50V and a typical gain (hFE) of 1000.

 

Integrated suppression diodes are included for inductive load driving, simplifying circuit design. The inputs are positioned opposite the outputs to facilitate board layout. This array is compatible with common logic families and is suitable for driving a wide range of loads such as solenoids, relay DC motors, LED displays, filament lamps, and high-power buffers.

 

The ULN2001A is available in a 16-pin DIP package and a small outline SO-16 package. These packages utilize a copper leadframe to reduce thermal resistance, enhancing performance and reliability in demanding applications.
