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 connected in parallel for higher current capability. 1 • • • 500-mA-Rated Collector Current (Single Output) High-Voltage Outputs: 50 V Output Clamp Diodes Inputs Compatible With Various Types of Logic 2 Applications • • • • • • • • • Relay Drivers Hammer Drivers Lamp Drivers Display Drivers (LED and Gas Discharge) Line Drivers Logic Buffers Stepper Motors IP Camera HVAC Valve and LED Dot Matrix Applications include relay drivers, hammer drivers, lamp drivers, display drivers (LED and gas discharge), line drivers, and logic buffers. The ULN2803A device has a 2.7-kΩ series base resistor for each Darlington pair for operation directly with TTL or 5-V CMOS devices.

These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. All voltage values, unless otherwise noted, are with respect to the emitter/substrate terminal GND. 6.2 ESD Ratings VALUE V(ESD) (1) (2) Electrostatic discharge Human body model (HBM), per ANSI/ESDA/JEDEC JS-001 (1) UNIT ±2000 Charged device model (CDM), per JEDEC specification JESD22-C101 (2) V ±500 JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
