ULN2004 : SMD/SMT Darlington Transistor Arrays

ULN2004 SMD/SMT 7-Channel Darlington Transistor Array - High-Power Interface

The ULN2004 is a versatile high-voltage, high-current Darlington transistor array designed for robust interfacing. It effectively bridges the gap between low-level logic circuits and various peripheral power loads. Each of its seven independent drivers can handle continuous load currents up to 500 mA, making it suitable for demanding applications. With an impressive output voltage capability of up to 95V, it can control significant power loads. These arrays feature open-collector outputs with integrated clamp diodes for enhanced protection against transients. The ULN2004 includes series input resistors, allowing direct operation with 5V TTL or CMOS logic. This makes it an excellent choice for interface needs that exceed the capabilities of standard logic buffers. It's perfect for driving relays, solenoids, stepping motors, and various displays.
