Overview
The ULQ2003ADR is a Darlington transistor array manufactured by Texas Instruments, featuring seven NPN channels in a single package. It operates with a maximum collector-emitter voltage of 50 V and supports a continuous DC collector current of 500 mA per channel. The device utilizes a surface-mount SOIC-Narrow-16 (SOIC-16) package. Its operational temperature range spans from -40°C to +85°C. This component integrates internal clamping diodes for inductive load driving applications.
Feature Summary
- Integrates seven independent high-voltage Darlington pairs within a compact integrated circuit structure.
- Includes built-in transient voltage suppression diodes connected to the common emitter node for inductive load protection.
- Designed for direct interfacing with TTL or CMOS logic circuits without requiring external driver components.
Applications
- Driving relays and solenoids in industrial control systems
- Actuating stepper motors and small DC motors
- Switching lamps and other high-current loads
Procurement Notes
Verify the specific suffix 'ADR' against the manufacturer's official documentation to confirm the reel packaging configuration and tape-and-reel specifications. Confirm RoHS compliance status through the latest datasheet revision notes. Ensure the procurement source provides valid traceability records for this discontinued or limited-stock item.
Selection Notes
Select this component when a surface-mount solution is required for driving multiple inductive loads. Compare the SOIC-16 footprint requirements against available PCB space. Verify that the 500 mA per-channel current rating meets the specific load demands. Consider thermal dissipation capabilities within the enclosed system environment.
Part Context
This part belongs to the ULQ2003A series, which represents the quad-compatible variant of the ULN2003 family. While the ULN2003AN uses a PDIP-16 through-hole package, the ULQ2003ADR adapts the same internal architecture for surface-mount technology. It serves as a bridge between low-power logic outputs and high-power switching requirements.
Replacement Considerations
Public confirmed substitute part numbers are not provided in the available documentation. Consult the manufacturer's obsolescence notices for potential recommended replacements or cross-reference with equivalent Darlington arrays from other vendors if availability is critical.
