ULN2803ADW Description

Short technical summary and product information.

The ULN2803ADW from Texas Instruments is a high-voltage, high-current Darlington transistor array. It comprises eight NPN Darlington pairs, each capable of handling 500mA collector current and featuring 50V outputs. Integrated common-cathode clamp diodes are included for switching inductive loads effectively.

 

This device is suitable for a variety of applications, including relay drivers, hammer drivers, lamp drivers, and display drivers. The built-in 2.7kΩ series base resistor for each Darlington pair allows for direct operation with TTL or 5V CMOS logic devices. The ULN2803ADW is housed in an 18-SOIC package, designed for surface mounting.

 

Key electrical characteristics include a 50V output voltage capability and a 500mA maximum collector current per output. The Vce saturation is specified at 1.6V typical at 500µA input current and 350mA output current. The operating temperature range is -40°C to 85°C.
