Description:

The ULN2003A is a classic and widely used 16-pin Darlington transistor array, perfect for driving high-current loads like relays, stepper motors, lamps, and solenoids directly from TTL or CMOS logic.

Specifications:

  • Function: 7-channel Darlington driver with internal flyback diodes
  • Package: 16-pin DIP (also available in SOIC, TSSOP)
  • Inputs: 7 TTL/CMOS-compatible logic inputs (pins 1–7)
  • Outputs: 7 open-collector outputs (pins 10–16), each rated for
    -Up to 50V
    -500mA continuous current
  • Pin 8: Ground
  • Pin 9: Common freewheeling diode connection (tie to load supply for inductive protection)
  • Features:
    -Built-in suppression diodes for inductive loads
    -Outputs can be paralleled for higher current
    -No VCC pin—power is drawn through the inputs
    -Compatible with Arduino, PIC, and other microcontrollers
  • Uses:
    -Stepper motor drivers (especially with 28BYJ-48 motors)
    -Relay control boards
    -LED matrix drivers
    -Logic buffers and line drivers
