Product Overview
The ULN2003 is a high-voltage, high-current Darlington array consisting of seven silicon NPN Darlington pairs. Each output is an open-collector type with a common emitter. Internal clamp diodes and base-emitter resistors are included for improved efficiency and reduced leakage. Each Darlington pair has a 2.7K base resistor, making it compatible with TTL and CMOS circuits at 5V. It can directly handle data that previously required standard logic buffers. With high operating voltage, large current, a sink current of up to 500mA, and the ability to withstand 50V in the off-state, the ULN2003 offers a robust solution for driving multiple interfaces. Applications include driving solenoids, relays, DC incandescent lamps, small motors, and LEDs.
