The ULN2004ADRG4 from Texas Instruments is a high-voltage, high-current Darlington transistor array designed for interfacing between low-level logic circuitry and multiple peripheral power loads. This integrated circuit consists of seven NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads.

Each of the seven Darlington pairs in the ULN2004ADRG4 can drive loads up to 500 mA and can withstand a peak current of 600 mA. The collector-current rating of each Darlington pair is 500 mA. The device can handle a maximum voltage of 50V, making it suitable for a wide range of applications in various electronic circuits.

With its ability to directly interface with TTL or 5V CMOS devices, the ULN2004ADRG4 is commonly used in relay drivers, stepper motor drivers, and LED displays among other applications. The inclusion of suppression diodes for inductive load driving makes this array especially valuable for controlling relays, solenoids, and other inductive components that require high current and/or high voltage switching.

The ULN2004ADRG4 comes in a 16-pin SOIC package, which is widely accepted for its compact size and ease of integration into various electronic systems. The device is characterized for operation from 0°C to 70°C, ensuring reliable performance across a range of environmental conditions.
