ULN2003BDR Description

Short technical summary and product information.

The ULN2003BDR from Texas Instruments is a 7-channel Darlington transistor array designed for high-voltage and high-current applications. Each of the seven NPN Darlington pairs features common-cathode clamp diodes for switching inductive loads. The device offers a switching voltage of up to 50V and a peak output current of 0.5A per channel, with a maximum collector current rating of 500mA per output.

 

This array is compatible with TTL and CMOS logic levels, featuring a 2.7kΩ series base resistor for direct operation. The ULN2003BDR is suitable for relay driver applications and other switching tasks requiring higher current capabilities than standard logic gates can provide.

 

The component is available in a 16-SOIC surface mount package, operating within a temperature range of -40°C to 105°C. Its output configuration is low-side, and it supports parallel input interfaces.

 

Note: This product is obsolete and new designs should consider an alternate product.
