Overview
The ULN2003AD16-U is a high-voltage, high-current Darlington transistor array manufactured by Diodes Incorporated. It contains seven open-collector NPN common-emitter pairs, each rated for a continuous collector current of 500 mA and capable of withstanding up to 50 V in the OFF state. The device features integrated suppression diodes for driving inductive loads and includes series input resistors optimized for direct interfacing with 5 V TTL or CMOS logic families. It is housed in a 16-lead Small Outline (SO-16) surface-mount package.
Feature Summary
- Seven independent high-current Darlington output channels
- Integrated clamp diodes for inductive load protection
- Direct compatibility with 5V TTL and CMOS logic inputs
Applications
- Relay driver circuits
- Stepping motor drive systems
- Solenoid control applications
Procurement Notes
Verify that the specific ordering suffix matches the required SO-16 package type. Confirm RoHS compliance status and lead-free specifications against the manufacturer's latest documentation before finalizing procurement orders.
Selection Notes
Select this component when interfacing low-level logic signals with high-voltage or high-current loads. Ensure the application requires 5V logic compatibility rather than the higher voltage requirements addressed by the ULN2004A variant.
Part Context
This part belongs to the ULN20xxA series of high-voltage Darlington arrays from Diodes Incorporated. It shares functional similarities with the ULN2002A and ULN2004A but is specifically configured with internal base resistors tailored for standard 5V digital logic interfaces.
Replacement Considerations
ULN2003AFS16-13 is an electrically identical alternative within the same product family offering the same SO-16 Type SM package configuration.
FAQ
What is the maximum continuous collector current per channel?
Each individual Darlington pair is rated for a maximum continuous collector current of 500 mA.
How does the device handle inductive loads?
The device includes integral clamp diodes connected to the COM pin to suppress back-EMF generated by switching inductive loads such as relays and solenoids.
Which logic families are supported by the input stage?
The internal base resistors allow the ULN2003A to interface directly with 5V TTL and CMOS logic families without requiring external level shifting components.
