ULN2003AIDR Description

Short technical summary and product information.

The Texas Instruments ULN2003AIDR is a versatile 7-channel Darlington transistor array. Each channel consists of an NPN Darlington pair with high-voltage outputs and common-cathode clamp diodes suitable for switching inductive loads. The array is designed for high-voltage, high-current applications, with a collector current rating of 500mA per single Darlington pair.

 

Key electrical specifications include a maximum switching voltage of 50V and a peak output current of 0.5A. The inputs are compatible with CMOS and TTL logic levels, with a typical delay time of 250ns. The operating temperature range is -40°C to 105°C.

 

This device is commonly used in applications such as relay drivers, hammer drivers, lamp drivers, and display drivers. The ULN2003AIDR is available in a 16-SOIC package, suitable for surface mount applications.

 

For higher current capability, the Darlington pairs can be paralleled. The ULN2003A devices feature a 2.7kΩ series base resistor for each Darlington pair, enabling direct operation with TTL or 5V CMOS devices.
