The ULN2003 datasheet provides specifications, ratings, pin connections, and application notes for the high‑voltage Darlington driver.
The ULN2003 is a high‑voltage, high‑current Darlington driver array comprising seven NPN Darlington pairs with integral clamp diodes. It is intended for driving inductive loads such as relays, lamps, and LED displays.
The document lists absolute maximum ratings, recommended operating conditions, electrical characteristics, test circuits, and safety notices, helping designers select appropriate packaging, ensure proper heat dissipation, and protect against over‑current or over‑voltage conditions.
