SLRS049C FEBRUARY1997 REVISED AUGUST 20041 POST OFFICE BOX 655303 DALLAS, TEXAS 75265D500-mA Rated Collector current (SingleOutput)DHigh-Voltage VDOutput Clamp DiodesDInputs Compatible With Various Types ofLogicDRelay Driver ApplicationsDCompatible with ULN2800A Series description/ordering informationThe ULN2803A is a high-voltage, high- current Darlingtontransistor array. The device consists of eight npn Darlington pairsthat feature high-voltage outputs with common-cathode clampdiodes for switching inductive loads.
diodes for switching inductive loads. The collector-current rating of each Darlington pair is 500 mA. The Darlington pairs may be connected in parallel for higher current capability. Applications include relay drivers, hammer drivers, lamp drivers, display drivers (LED and gas discharge), line drivers, and logic buffers.
