Product Description
Product Overview
The ULN2003 is a high-voltage, high-current Darlington transistor array featuring seven open-collector common-emitter pairs, each rated at 500mA. It includes output clamp diodes for inductive load driving and inputs compatible with various logic types. Designed for relay-driver applications, this array is capable of driving a wide range of loads including solenoids, DC motors, LED displays, filament lamps, thermal print-heads, and high-power buffers. The inputs and outputs are pinned in opposition to simplify board layout.
