ULN2004AN Description

Short technical summary and product information.

The ULN2004AN from Texas Instruments is a high-voltage, high-current Darlington transistor array designed for driving inductive loads. Each of the seven NPN Darlington pairs features common-cathode clamp diodes, providing robust performance in demanding applications.

 

This array boasts a 50V output voltage capability and a 500mA collector current rating for each individual output. The Darlington pairs can be paralleled to achieve higher current handling when needed. Each input includes a 10.5kΩ series base resistor, facilitating direct operation with various logic types.

 

Applications for the ULN2004AN include relay drivers, hammer drivers, lamp drivers, and display drivers. It is housed in a 16-pin PDIP (Plastic Dual In-line Package) and is suitable for through-hole mounting. The operating temperature range is -40°C to 70°C.

 

Key electrical characteristics include its 7-channel configuration, low-side output configuration, and parallel interface. The device is designed for reliability and ease of integration into power control circuits.
