8-Digit Darlington Current Driver ULN2803A FEATURES • • • • • • • 8 Darlington Arrays per Package 500 mA Rated Collector Current (Single Output) Output voltage 50V Output Clamp Diodes Input Compatible with Various Types of Logic Relay-Driver Applications Input pins placed opposite to output pins to simplify layout SOP-18 APPLICATION • • • • • • Relay Drivers Stepper and DC Brushed Motor Drivers Lamp Drivers Display Drivers Line Drivers Logic Buffers DIP-18 ORDERING INFORMATION DESCRIPTION The ULN2803A is monolithic high-voltage, high-current Darlington transistor arrays. Each consists of eight NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads. The collector-current rating of a single Darlington pair is 500 mA. The Darlington pairs may be paralleled for higher current capability. Applications include relay drivers, hammer drivers, lamp drivers, display drivers (LED and gas discharge), line drivers, and logic buffers.
