ULN2003ADR AI Analysis:
Datasheet, Specs, Alternatives & ECAD

It is commonly used as a driver for relays, solenoids, lamps, and LED displays, acting as an interface between low-power logic and higher-power loads.

It supports up to 50V output, 500mA collector current per channel, and is compatible with TTL and 5V CMOS logic.

Review the power dissipation limits, especially when multiple channels are active simultaneously, and ensure the input voltage levels match the 2.7kΩ base resistor requirements.

The part is currently active and widely available from major distributors, presenting low sourcing risk.
