The ULQ2001, ULQ2003, and ULQ2004 are high voltage, high current darlington arrays containing seven open collector darlington pairs with common emitters.
Each channel is rated at 500mA and can withstand peak currents of 600mA.
The arrays have integrated suppression diodes for inductive load driving and are compatible with all common logic families.
They can be used for driving a wide range of loads including solenoids, relays, DC motors, LED displays, filament lamps, thermal print-heads, and high power buffers.
The ULQ2001A/2003A/2004A are supplied in 16 pin plastic DIP packages with a copper lead-frame to reduce thermal resistance, and are also available in small outline package (SO-16) as ULQ2003D1/2004D1.
The document also includes diagrams, pin configurations, maximum ratings, electrical characteristics, test circuits, and package mechanical data for the ULQ200XA/XD1.
The document also includes a revision history and disclaimers from STMicroelectronics.
