ULN2003A Integrated Circuit 16Pin
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
