ULN2003ADR
Brand: Texas Instruments
The ULN2003ADR is a classic 7-channel Darlington transistor array with integrated clamp diodes, driving relays, solenoids, lamps and stepper-motor coils directly from logic-level inputs without external flyback protection. Its 500 mA per-channel rating and decades of proven field use make it a go-to driver array for low-cost relay and stepper-motor interfacing.
