ULN2003 IC high-voltage, high-current Darlington transistor array IC DIP16 UTC ULN2003L

Product Overview: A 16-pin through-hole integrated circuit comprising seven high-voltage, high-current NPN Darlington transistor pairs. It features internal common-cathode clamp diodes, making it an industry standard for safely switching inductive loads such as relays, solenoids, DC motors, and stepper motors. It features an internal 2.7kΩ base resistor for each channel, allowing it to interface directly with 5V logic families.
