The ULN200xA ULN200xD1 is a high voltage, high current darlington array with seven darlington pairs. Each driver has an output current of 500mA (600mA peak) and an output voltage of 50V. It includes integrated suppression diodes for inductive loads. The outputs can be paralleled for higher current. The inputs are pinned opposite the outputs to simplify layout. It is suitable for driving a wide range of loads including solenoids, relays, DC motors, LED displays, filament lamps, thermal printheads, and high power buffers.
The ULN200xA and ULN200xD1 families are high‑voltage, high‑current Darlington arrays offering seven open‑collector drivers per package. Each driver can handle up to 500 mA continuous (600 mA peak) and includes integrated suppression diodes for inductive loads. The devices are compatible with TTL, CMOS, PMOS, and DTL logic families and are suitable for driving solenoids, relays, DC motors, LED displays, filament lamps, and thermal printheads.
Both families are offered in 16‑pin DIP and narrow‑outline SO packages. The ULN2001A‑2004A versions use a plastic DIP leadframe for reduced thermal resistance, while the ULN2001D1‑2004D1 versions are supplied in SO‑16 packages. Key electrical limits include a 50 V output voltage rating and a -20 °C to 85 °C operating temperature range.
