ULN2803A-EV Description

Short technical summary and product information.

The ULN2803A-EV from EVVO Semiconductor is a high-voltage, high-current Darlington driver IC. It is composed of 8 NPN Darlington pairs, all sharing a common emitter and featuring open-collector outputs. Each pair includes a 2.7 kΩ resistor in series, ensuring compatibility with TTL and 5V CMOS logic levels without requiring a separate logic buffer.

This device is designed for applications requiring significant current handling, with a sink current capability of up to 500mA per channel and a withstand voltage of 50V. It is suitable for driving high-load currents and provides solutions for various interface needs. The ULN2803A-EV also includes clamp diodes for switching inductive loads, enhancing its robustness in demanding applications.

Available in DIP-18 and SOP-18 packages, the ULN2803A-EV operates over a wide temperature range from -40°C to 85°C. Its high-gain Darlington array structure and direct compatibility with common logic families make it a versatile component for applications such as relay drivers, stepper motor drivers, and solenoid drivers.
