ULN2803 Darlington Driver Array

An 8-channel Darlington transistor array designed for driving high-current loads such as relays, stepper motors, solenoids, and LED arrays directly from TTL or CMOS logic. The ULN2803 integrates clamp diodes for inductive-load protection and provides robust current handling, making it suitable for automation systems, microcontroller interfaces, and general-purpose switching applications. Packaged in a DIP-18 format for easy prototyping and PCB integration.
