Introduction

AI Translation

The ULN2803 is a high-voltage, high-current Darlington transistor array containing eight NPN Darlington pairs with open-collector common-emitter outputs per device. Each pair is rated at 500mA. Integral suppression diodes for inductive load driving are included, with inputs and outputs pinned in opposing configuration to simplify PCB layout. The device is capable of driving a wide range of loads, including solenoids, relays, DC motors, LED displays, filament lamps, thermal printheads, and high-power buffers. The ULN2803 is available in an 18-pin SOP package.
