ULN2001A Datasheet PDF – Seven Darlington Array

Part Number: ULN2001A

Function: Seven Darlington Array

Package: DIP, SOP 16 Pin Type

Manufacturer: STMicroelectronics


ULN2001A datasheet



The ULN2001, ULN2002, ULN2003 and ULN2004 are high-voltage, high-current Darlington
arrays each containing seven open collector Darlington pairs with common emitters. Each
channel is rated at 500 mA and can withstand peak currents of 600 mA. Suppression diodes are included for inductive load driving and the inputs are pinned opposite the outputs to simplify board layout.

The ULN2001A, ULN2002A, ULN2003A and 2004A are supplied in a 16-pin DIP package with a copper leadframe to reduce thermal resistance.



1. Seven Darlingtons per package

2. Output current 500 mA per driver (600 mA peak)

3. Output voltage 50 V

4. Integrated suppression diodes for inductive loads

5. Outputs can be paralleled for higher current

6. TTL/CMOS/PMOS/DTL compatible inputs

7. Inputs pinned opposite outputs to simplify layout
