ULN2064B - ULN2066B ULN2074B - ULN2076B ULN2068B - ULN2070B are Schmidt circuits with an output current of 1.5 A, a minimum working voltage of 50 V, a maximum working voltage of 35 V, integrated suppression diodes, and are compatible with 5 V logic circuits and 6-15 V CMOS and PMOS circuits.
The ULN2064B‑ULN2076B series are quad Darlington switches designed to interface logic circuits with high‑current, high‑voltage loads. Each device includes four NPN Darlington transistors, integral suppression diodes, and, for the ULN2074B/ULN2076B, isolated pinouts.
The document lists electrical characteristics such as a 1.5 A output current, 50 V minimum breakdown voltage, and 35 V sustaining voltage, as well as mechanical data, mounting guidelines, and example applications like LED drivers. It also contains absolute maximum ratings, typical application circuits, and a legal disclaimer.
