Description

The ULN2803ADW 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. The collector-current rating ofeach Darlington pair is 500 mA. The Darlington pairs may beconnected in parallel for higher current capability.Applications include relay drivers, hammer drivers, lamp drivers, display drivers (LED and gas discharge), linedrivers, and logic buffers. The ULN2803A has a 2.7-kΩ series base resistor for each Darlington pair for operationdirectly with TTL or 5-V CMOS devices. ULN2803ADW Applications • 500-mA Rated Collector Current (SingleOutput)• High-Voltage Outputs . . . 50 V• Output Clamp Diodes• Inputs Compatible With Various Types ofLogic• Relay Driver Applications• Compatible with ULN2800A Series
