Texas Instruments ULN2004AI Datasheet

The ULN2004AI Darlington transistor array provides seven NPN Darlington pairs with high‑voltage outputs and common‑cathode clamp diodes, suitable for relay, lamp, and logic driver applications. Each pair is rated for 500 mA collector current and can be paralleled for higher current.

The device is offered in PDIP, SOIC, and SOP packages, operates from –40 °C to 105 °C, and includes detailed electrical, mechanical, and safety specifications.
