The ULN2803AN from Texas Instruments is a high-voltage, high-current Darlington transistor array. It comprises eight NPN Darlington pairs, each with a 500-mA collector current rating and integrated common-cathode clamp diodes for switching inductive loads.
This device is suitable for various applications including relay drivers, hammer drivers, lamp drivers, and display drivers. It features 50V high-voltage outputs and includes a 2.7-kΩ series base resistor for each Darlington pair, enabling direct operation with TTL or 5V CMOS logic devices.
The ULN2803AN is available in an 18-DIP (Through Hole) package, with a body size of 22.48 mm x 6.35 mm. Its operating temperature range is -40°C to 85°C.
Key electrical characteristics include a 50V collector-emitter voltage and a 500mA collector current. The saturation voltage is a maximum of 1.6V at 500µA input current and 350mA output current.
