Overview
The ULN2003ADRG4 is a high-voltage, high-current Darlington transistor array manufactured by Texas Instruments. It integrates seven independent NPN Darlington pairs within a single SOIC-16 surface-mount package. Each channel provides a continuous collector current of 500 mA and supports a maximum collector-emitter voltage of 50 V. The device includes integrated clamp diodes across each input and output to suppress inductive voltage spikes from loads such as relays or solenoids. Designed for TTL and CMOS compatibility, it operates reliably within an ambient temperature range of -40°C to +85°C.
Feature Summary
- Integrates seven independent high-voltage Darlington transistor channels with common emitters
- Includes built-in transient voltage suppression diodes for inductive load protection
- Features internal base resistors ensuring direct interface with standard logic families
Applications
- Relay driver circuits
- Stepper motor control interfaces
- Solenoid actuation systems
Procurement Notes
Verify the specific suffix 'G4' against the manufacturer's official documentation to confirm RoHS compliance status and lead-free manufacturing specifications. Ensure the ordering part number matches the exact SOIC-16 tape-and-reel configuration required for automated assembly processes.
Selection Notes
Select this component when a compact surface-mount solution is required for driving multiple inductive loads simultaneously. The SOIC-16 package offers space efficiency compared to through-hole alternatives while maintaining identical electrical performance characteristics suitable for general-purpose switching applications.
Part Context
This part belongs to the ULN2003A family of high-voltage Darlington arrays produced by Texas Instruments. It serves as the surface-mount equivalent to the traditional through-hole ULN2003AN, providing the same functional architecture in a modern packaging format designed for automated PCB assembly workflows.
Replacement Considerations
The ULN2003DR is a compatible alternative offering identical pinout and electrical specifications in the same SOIC-16 package. Verify that any substitute maintains the 500 mA per-channel current rating and integrated clamp diode functionality.
