ULN2803A

ULN2803A DARLINGTON TRANSISTOR ARRAY SLRS049 – FEBRUARY1997 1POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 � 500 mA Rated Collector Current (Single Output) � High-Voltage Outputs . . . 50 V � Output Clamp Diodes � Inputs Compatible With Various Types of Logic � Relay Driver Applications � Compatible with ULN2800A Series description The ULN2803A is a monolithic high-voltage, high-current Darlington transistor array. The device 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 each 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. The ULN2803A has a 2.7-kW series base resistor for each Darlington pair for operation directly with TTL or 5-V CMOS devices. The ULN2803A is offered in a standard 18-pin dual in-line (N) package. The device is characterized for operation over the temperature range of –20°C to 85°C. logic symbol† † This symbol is in accordance with ANSI/IEEE Std 91-1984 and IEC Publication 617-12. 12 13 14 15 16 17 18 10 7C 6C 5C 4C 3C 2C 1C COM 7 6 5 4 3 2 1 1B 2B 3B 4B 5B 6B 7B CLAMP × 11 8C 8 8B logic diagram (positive logic) 8C 7C 6C 5C 4C 3C 2C 7 6 5 4 3 2 1 7B 6B 5B 4B 3B 2B 1B 11 12 13 14 15 16 17 COM 8 8B 10 1C 18 Copyright  1997, Texas Instruments IncorporatedPRODUCTION DATA information is current as of publication date.
