The ULN2803A is a high-voltage, high-current Darlington driver IC from Vishay Dale, featuring 8 NPN Darlington pairs with a common emitter. Each unit has an open-collector output and includes a 2.7KΩ resistor for compatibility with TTL and 5V CMOS logic levels without requiring a buffer.
This transistor array is designed for applications requiring significant current handling, with a sink current of up to 500mA per channel and a withstand voltage of 50V. The Vce saturation voltage is a maximum of 1.6V at 500µA input current and 350mA collector current. It operates within a temperature range of -40°C to 150°C.
The ULN2803A is available in a surface mount 18-SOIC package. Its robust design makes it suitable for driving various loads, including relays, solenoids, and stepper motors, providing reliable interface solutions for demanding applications.
