The ULN2000A/L series are high‑voltage, high‑current Darlington arrays designed for interfacing low‑level logic with loads such as relays, solenoids, stepping motors, LEDs and heaters. The series includes variants (ULN2001A/L, ULN2025A/L, etc.) that differ in input voltage compatibility and output current capability.
Key specifications include a maximum output voltage of 50 V, continuous output current up to 600 mA per driver, and operating temperature from –20 °C to +85 °C. Devices are offered in 16‑pin DIP (suffix A) and 16‑lead SOIC (suffix L) packages with detailed mechanical dimensions provided.
| Operating Temperature Range | -20 °C to +85 °C |
|---|---|
| Storage Temperature Range | -55 °C to +150 °C |
| Package Power Dissipation (suffix A) | 60 °C/W |
| Body Length (DIP) | 0.735/0.785 in |
The series is offered in a 16‑pin dual‑in‑line (suffix A) and a 16‑lead surface‑mount (suffix L) package.
The devices operate from –20 °C up to +85 °C.
