ULN2004A Description

Short technical summary and product information.

The ULN2004A is a high-voltage, high-current Darlington Array containing seven open collector Darlington pairs with common emitters. Each channel is rated at 500 mA and can withstand peak currents of 600 mA. The output voltage rating is 50 V.

 

Integrated suppression diodes are included for inductive load driving, simplifying circuit design. The inputs are pinned opposite the outputs to facilitate board layout. The ULN2004A interfaces to common logic families, specifically designed for 6 - 15 V CMOS and PMOS logic.

 

These versatile devices are suitable for driving a wide range of loads, including solenoids, relay DC motors, LED display filament lamps, thermal printheads, and high-power buffers. The ULN2004A is supplied in a 16-pin DIP package with a copper leadframe to reduce thermal resistance.

 

Key specifications include an output current of 500 mA per driver (600 mA peak), an output voltage of 50 V, and a typical hFE of 1000. The inputs are TTL/CMOS/PMOS/DTL compatible.
