ULN2001D1 Description

Short technical summary and product information.

The ULN2001D1 from STMicroelectronics is a versatile Darlington Array designed for high-voltage and high-current applications. It contains seven open-collector Darlington pairs, each rated for 500 mA continuous output current and capable of handling peak currents up to 600 mA. The output voltage rating is 50 V.

 

This array includes integrated suppression diodes, making it suitable for driving inductive loads such as solenoids, relays, and DC motors. The inputs are compatible with common logic families like TTL, CMOS, and PMOS, and are positioned opposite the outputs to simplify PCB layout. The ULN2001D1 is available in both 16-pin DIP and SO-16 packages, with the DIP version featuring a copper leadframe for reduced thermal resistance.

 

These devices are useful for a wide range of applications, including driving LED displays, filament lamps, thermal printheads, and acting as high-power buffers in various electronic systems.
