ULN2004AD Description

Short technical summary and product information.

The ULN2004AD from Texas Instruments is a high-voltage, high-current Darlington transistor array. Each device consists of seven NPN Darlington pairs, offering high-voltage outputs suitable for switching inductive loads due to integrated common-cathode clamp diodes.

 

Key electrical specifications include a collector current rating of 500mA per single output, which can be paralleled for higher current capability. The output voltage rating is 50V. The inputs are compatible with various logic types and feature an inverting input configuration. The device operates with a parallel interface.

 

Packaged in a 16-SOIC surface-mount package, the ULN2004AD is designed for applications such as relay drivers, hammer drivers, lamp drivers, display drivers (LED and gas discharge), line drivers, and logic buffers. Its operating temperature range is -20°C to 70°C.

 

This array is well-suited for interfacing with low-logic-level circuits to high-power loads, providing a robust solution for demanding driver applications.
