ULQ2003AN Description

Short technical summary and product information.

The ULQ2003AN from Texas Instruments is a high-voltage, high-current Darlington transistor array. It comprises seven NPN Darlington pairs, each equipped with common-cathode clamp diodes suitable for switching inductive loads. The device offers 50V high-voltage outputs and a collector current rating of 500mA per output, with the capability to parallel pairs for increased current capacity.

 

Designed for versatility, the ULQ2003AN features inputs compatible with TTL and 5V CMOS logic, facilitated by a 2.7kΩ series base resistor for each Darlington pair. Its operating temperature range is -40°C to 85°C. The array is available in a 16-pin PDIP through-hole package, making it suitable for various PCB mounting requirements.

 

Common applications for the ULQ2003AN include relay drivers, hammer drivers, lamp drivers, and display drivers (LED and gas discharge). It also serves as a line driver and logic buffer in electronic circuits.
