ULN2003AINSR Description

Short technical summary and product information.

The ULN2003AINSR from Texas Instruments is a high-voltage, high-current Darlington transistor array. It comprises seven NPN Darlington pairs, each equipped with common-cathode clamp diodes suitable for switching inductive loads. The device offers 50V high-voltage outputs and a collector current rating of 500mA per single Darlington pair.

 

This array is designed for direct compatibility with TTL or 5V CMOS devices, featuring a 2.7kΩ series base resistor for each Darlington pair. The inputs are compatible with various logic types, and the output configuration is low-side.

 

The ULN2003AINSR is available in a 16-SOIC surface mount package. Its operating temperature range is -40°C to 105°C (TA). Applications include relay drivers, hammer drivers, lamp drivers, and display drivers.

 

Key electrical characteristics include a switching voltage of up to 50V, a peak output current of 0.5A, and a typical delay time of 250ns. The typical voltage at the lowest specified current is 900mV, with a typical output current off of 50µA.
