Overview
The ULN2003TTR is a high-voltage, high-current seven Darlington array manufactured by STMicroelectronics in a TSSOP16 surface-mount package. It contains seven open-collector NPN Darlington pairs with common emitters, each rated for a continuous collector current of 500 mA and capable of withstanding peak currents up to 600 mA. The device features an output voltage rating of 50 V and includes integrated suppression diodes for driving inductive loads. Designed for TTL and CMOS logic compatibility, it interfaces directly with standard logic families. The component operates within an ambient temperature range of -40 °C to +85 °C.
Feature Summary
- Seven independent NPN Darlington transistor channels per package
- Integrated flyback diodes for inductive load protection
- Direct interface capability with TTL and CMOS logic families
- Outputs arranged opposite inputs to simplify printed circuit board layout
Applications
- Driving solenoids and relays
- Controlling DC motors
- Powering LED displays and filament lamps
- Operating thermal printheads
- Serving as high-power buffers
Procurement Notes
Verify the specific ordering code matches the required TSSOP16 package configuration. Confirm that the tape and reel packaging aligns with automated assembly requirements. Ensure the selected part number corresponds to the correct logic family compatibility specifications for the target application design.
Selection Notes
Select this component when space constraints require a surface-mount solution over traditional DIP packages. Consider the thermal resistance characteristics of the TSSOP16 package relative to the expected power dissipation. Verify that the 500 mA per channel rating meets the load requirements without necessitating parallel output configurations.
Part Context
This part belongs to the ULN2001/2002/2003/2004 series of high-voltage Darlington arrays. While other variants offer different logic input thresholds or alternative packages like SO-16 and DIP-16, the ULN2003TTR specifically provides the TSSOP16 form factor. This package option reduces application space compared to through-hole alternatives while maintaining identical electrical performance characteristics.
