The ULN2003A from UMW Youtai Semiconductor is a versatile Darlington array driver IC designed for high-voltage and high-current applications. It comprises seven NPN Darlington pairs, each with an open-collector output and a serial 2.7KΩ resistor for TTL and 5V CMOS compatibility.
This device is capable of sinking up to 500mA per channel with a withstand voltage of 50V, making it suitable for driving various loads such as relays, solenoids, and DC motors. The ULN2003A operates within a wide voltage range and includes clamp diodes for switching inductive loads.
Packaged in a 16-SOP surface-mount configuration, the ULN2003A operates from -40°C to 85°C. Its design facilitates direct connection to logic devices without the need for buffer circuits, simplifying interface designs.
Key electrical characteristics include a typical output saturation voltage of 1.6V at 350mA and a typical input current of 1.35mA when the output is on. The device also offers a typical turn-on and turn-off delay of 1.0 µS.
