The ULN2003D1 from STMicroelectronics is a high-voltage, high-current Darlington array IC containing seven open-collector Darlington pairs with common emitters. Each channel is rated for 500mA continuous output current and can withstand peak currents of 600mA, with a maximum output voltage of 50V.
This device includes integrated suppression diodes for inductive load driving, making it suitable for applications involving relays, solenoids, DC motors, and LED displays. The inputs are TTL/CMOS/PMOS/DTL compatible and are pinned opposite the outputs to simplify board layout. The ULN2003D1 is supplied in a 16-pin SOIC package, designed for surface mounting.
Its versatility makes it useful for a wide range of loads, including solenoids, relays, DC motors, LED displays, filament lamps, and thermal printheads. The parallel interface capability allows for higher current output when needed.
