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. The collector-current rating ofeach Darlington pair is 500 mA. The Darlington pairs may beconnected in parallel for higher current include relay drivers , hammer drivers , lamp drivers , display drivers (LED and gas discharge), linedrivers, and logic buffers. The ULN2803A has a series base resistor for each Darlington pair for operationdirectly with TTL or 5-V CMOS INFORMATIONTAPACKAGE ORDERABLEPART NUMBERTOP-SIDEMARKINGPDIP (N)Tube of 20 ULN2803 ANULN2803AN 40 C to 85 CSOIC (DW)Tube of 40 ULN2803 ADWULN2803A 40C to 85 CSOIC (DW)Reel of 2000 ULN2003 ADWRULN2803A Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines areavailable at 2004, Texas Instruments Incorporated Please be aware that an important
