ULN2004 SMD/SMT 7-Channel Darlington Transistor Array
The ULN2004 is a 7-channel Darlington transistor array. It facilitates interfacing between low-level logic and power loads. Each driver supports continuous load currents up to 500 mA. The array provides an output voltage capability of up to 95V. Outputs are open-collector with integrated clamp diodes for transient protection. Series input resistors enable direct operation with 5V TTL or CMOS logic. This device is suitable for driving relays, solenoids, and stepping motors. It addresses interface requirements beyond standard logic buffers.
