ULN2003ADR

Texas Instruments · Darlington Transistor Arrays · SOIC-16

ULN2003ADR from Texas Instruments, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 1B input Channel 1 Darlington base input. TTL/5 V CMOS compatible via internal 2.7 kΩ series base resistor. Absolute maximum input voltage 30 V.
2 2B input Channel 2 Darlington base input. TTL/5 V CMOS compatible via internal 2.7 kΩ series base resistor.
3 3B input Channel 3 Darlington base input. TTL/5 V CMOS compatible via internal 2.7 kΩ series base resistor.
4 4B input Channel 4 Darlington base input. TTL/5 V CMOS compatible via internal 2.7 kΩ series base resistor.
5 5B input Channel 5 Darlington base input. TTL/5 V CMOS compatible via internal 2.7 kΩ series base resistor.
6 6B input Channel 6 Darlington base input. TTL/5 V CMOS compatible via internal 2.7 kΩ series base resistor.
7 7B input Channel 7 Darlington base input. TTL/5 V CMOS compatible via internal 2.7 kΩ series base resistor.
8 E power_in Common emitter shared by all seven Darlington channels. Typically tied to ground. Total emitter-terminal current rated -2.5 A max.
9 COM power_in Common cathode node for the internal flyback clamp diodes. Connect to the load supply rail (up to 50 V) when driving inductive loads such as relays or stepper motors.
10 7C output Channel 7 Darlington collector output. Open-collector, rated 500 mA continuous single-output collector current, 50 V max VCE.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (42 pp, sha256 0151daa4ffa9135f, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
