TEXAS INSTRUMENTS ULN2003AI Manual(1)
The ULN2003A is a high‑voltage, high‑current Darlington transistor array that contains seven NPN Darlington pairs with common‑cathode clamp diodes. It is designed for relay, lamp, display, line‑driver, and logic‑buffer applications and can be driven directly from TTL or 5‑V CMOS devices.
The document lists absolute maximum ratings, detailed electrical and switching characteristics, ordering information for PDIP, SOIC, TSSOP and PW packages, and mechanical dimensions. It also includes a notice on warranty, availability, and usage terms.
