                                                                                                    ULN2003A is a high-voltage, high-current darlington array containing seven open collector darlington pairs with common emitters. Each channel is rated at 500mA and can withstand peak currents of 600mA. Suppression diodes are included for inductive load driving and the inputs are pinned opposite the outputs to simplify board layout. Device interfaces to all common logic families: 5V TTL, CMOS. It is useful for driving a wide range of loads including solenoids, relay DC motors, LED display filament lamps, thermal printheads and high-power buffers.
