The document describes the features and characteristics of the ULN2003A-ULN2004A and ULN2001A-ULN2002A series seven Darlington arrays chips, including each chip containing seven open collector Darlington pairs, output current of 500mA (peak of 600mA), output voltage of 50V, integrated suppression diodes for inductive load driving, etc.
The ULN2001A‑2004A family consists of seven‑channel Darlington driver arrays available in DIP‑16 and SO‑16 packages. Each channel can drive up to 500 mA continuously (600 mA peak) and includes integrated suppression diodes for inductive loads, making them suitable for solenoids, relays, LED displays, filament lamps, and other loads.
Key specifications include a maximum output voltage of 50 V, continuous collector current of 500 mA, continuous base current of 25 mA, and an operating ambient temperature range of –20 °C to 85 °C. The devices are rated for a junction temperature of 150 °C and have a thermal resistance of up to 70 °C/W. Mechanical dimensions for the DIP‑16 package are provided, with a pin spacing of 2.54 mm.
