ULN2003A Description

Short technical summary and product information.

The ULN2003A is a versatile 7-channel Darlington array driver IC manufactured by Nexperia USA Inc. This component is designed for high-voltage and high-current applications, offering an output current capability of up to 500mA per channel and a withstand voltage of 50V.

Each channel consists of a 2.7kΩ resistor in series with a NPN Darlington pair, making it directly compatible with TTL and 5V CMOS logic levels without requiring buffer circuits. The open-collector outputs are suitable for driving various loads.

Available in DIP-16-300-2.54 and SOP-16-225-1.27 packages, the ULN2003A operates within a wide temperature range of -40°C to 85°C. Its design includes clamp diodes for switching inductive loads, making it ideal for applications such as relay drivers, clamp drivers, stepper motor drivers, and solenoid drivers.
