The ULN2803A device is a high-voltage, high-current 1• 500-mA-Rated Collector Current Darlington transistor array. The device consists of (Single Output) eight NPN Darlington pairs that feature high-voltage • High-Voltage Outputs: 50 V outputs with common-cathode clamp diodes for • Output Clamp Diodes switching inductive loads. The collector-current rating • Inputs Compatible With Various of each Darlington pair is 500 mA. The Darlington pairs may be connected in parallel for higher current Types of Logic capability. • Relay-Driver Applications Applications include relay drivers, hammer drivers, • Compatible with ULN2800A Series lamp drivers, display drivers (LED and gas discharge), line drivers, and logic buffers. The 2 Applications ULN2803A device has a 2.7-kΩ series base resistor • Relay Drivers for each Darlington pair for operation directly with TTL or 5-V CMOS devices.
