High-Voltage, High-Current Darlington Transistor Arrays
Log in or register to manage email notifications about changes to datasheets or PCNs for this part.
The ULN2002A, ULN2003A, and ULN2004A are high-voltage, high-current Darlington arrays each containing seven open collector common emitter pairs. Each pair is rated at 500mA. Suppression diodes are included for inductive load driving. The inputs and outputs are pinned in opposition to simplify board layout.
Device options are designed to be compatible with common logic families:
These devices are capable of driving a wide range of loads including solenoids, relays, DC motors, LED displays, filament lamps, thermal print-heads, and high-power buffers.
The ULN2002A, ULN2003A, and ULN2004A are available in both a small outline 16-pin package (SO-16) and a PDIP-16 package. The ULN2003A has an additional TSSOP-16 (Type CJ) package available for small footprint requirements.
