Description
ULN2004AN Darlington Transistor Array IC DIP-16
The ULN2004AN Darlington Transistor Array IC is a high-voltage, high-current driver IC containing seven Darlington transistor pairs with common emitters. It is designed for interfacing between low-level logic circuits and high-power loads. With built-in flyback diodes, it provides protection when driving inductive loads such as relays and motors. The DIP-16 package makes it easy for prototyping and PCB assembly. The ULN2004AN is widely used in relay driving, stepper motor control, LED driving, solenoids, and automation systems.
