ULN2003TTR Description

Short technical summary and product information.

The STMicroelectronics ULN2003TTR is a high-voltage, high-current Darlington array IC. It is designed for applications requiring the interfacing of low-logic-level digital circuits with high-power loads such as relays, solenoids, and lamps.

 

This component features seven independent NPN Darlington pairs, each capable of delivering up to 500mA of continuous output current. The outputs are configured as low-side switches and are inverting, meaning a high logic input results in a low output.

 

The ULN2003TTR operates over a temperature range of -40°C to 85°C (TA) and is housed in a 16-TSSOP surface mount package. Its parallel interface simplifies integration into various digital systems.

 

Key specifications include 7 outputs, NPN output type, 500mA current capability, and an inverting input configuration. The device is suitable for driving inductive loads like relays and solenoids.
