ULN2803 SOIC-18 Wide – 8-Channel Darlington Transistor Array Driver IC
memory Technical Parameters & Datasheet Summary
SKU: ANIL2647The ULN2803 is an 8-channel Darlington transistor array driver IC designed to interface logic-level signals with higher current/voltage loads. Each channel can handle up to 500mA at 50V, making it ideal for driving relays, stepper motors, lamps, solenoids, and LED displays.
Packaged in a SOIC-18 wide surface-mount package, the ULN2803 is widely used in automation, robotics, industrial control, and embedded systems where multiple loads need to be controlled by microcontrollers or logic circuits. Its built-in suppression diodes make it especially suited for inductive load driving.
Features:
- 8-channel Darlington transistor array driver IC
- High current handling: up to 500mA per channel
- High voltage tolerance: up to 50V output
- Built-in clamp diodes for driving inductive loads
- TTL/CMOS compatible inputs
