    The ULN2003ADR is a high-voltage, high-current Darlington transistor array integrated circuit (IC) manufactured by Texas Instruments. It is designed for interfacing between low-level logic signals and high-current loads such as relays, motors, and lamps in various applications.

    Key Features:

    • Darlington Transistor Array: Contains seven Darlington pairs, each capable of driving loads up to 500 mA (600 mA peak) per channel.
    • Input Compatibility: Compatible with TTL (Transistor-Transistor Logic) and CMOS (Complementary Metal-Oxide-Semiconductor) logic levels.
    • Output Voltage: Handles output voltages up to 50V.
    • Built-in Clamp Diodes: Provides protection against inductive loads.
    • Package Type: Available in various packages including SOIC (Small Outline Integrated Circuit) and TSSOP (Thin Shrink Small Outline Package) for different application requirements.

    Typical Applications:

    • Relay Drivers: Controls relay coils directly.
    • Stepper Motor Drivers: Drives stepper motors in various motion control applications.
    • Lamp Drivers: Switches and controls lamps and incandescent displays.
    • LED Drivers: Provides current to drive LED arrays.
    • Peripheral Drivers: Interfaces with various peripheral devices requiring high-current switching.

    Advantages:

    • High Current Capability: Suited for applications requiring high-current switching.
    • Ease of Use: Simplifies interfacing between low-level logic and high-current loads.
    • Integrated Protection: Built-in clamp diodes protect against inductive kickback.
    • Compact Design: Available in compact surface-mount packages, facilitating space-constrained designs.
