ULN2003AN

XBLW · Darlington Transistor Arrays · DIP-16

ULN2003AN from XBLW, in a DIP-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	Input 1 - base of Darlington pair 1, TTL/CMOS compatible logic input (VI up to 30 V absolute max, VIN(ON) typ 2.5 V).
2	2B	input	Input 2 - base of Darlington pair 2, TTL/CMOS compatible logic input.
3	3B	input	Input 3 - base of Darlington pair 3, TTL/CMOS compatible logic input.
4	4B	input	Input 4 - base of Darlington pair 4, TTL/CMOS compatible logic input.
5	5B	input	Input 5 - base of Darlington pair 5, TTL/CMOS compatible logic input.
6	6B	input	Input 6 - base of Darlington pair 6, TTL/CMOS compatible logic input.
7	7B	input	Input 7 - base of Darlington pair 7, TTL/CMOS compatible logic input.
8	E	power_in	Ground - common emitter return for all seven Darlington pairs. Connect to system ground.
9	COM	power_in	Common cathode of the seven internal free-wheeling clamp diodes. Tie to the positive supply of the inductive load (e.g. relay/motor coil supply, up to 60 V) so the diodes can absorb flyback energy.
10	7C	output	Output 7 - open-collector Darlington output, sinks up to 500 mA continuous (600 mA peak), VCE up to 60 V.
11	6C	output	Output 6 - open-collector Darlington output, sinks up to 500 mA continuous, VCE up to 60 V.
12	5C	output	Output 5 - open-collector Darlington output, sinks up to 500 mA continuous, VCE up to 60 V.
13	4C	output	Output 4 - open-collector Darlington output, sinks up to 500 mA continuous, VCE up to 60 V.
14	3C	output	Output 3 - open-collector Darlington output, sinks up to 500 mA continuous, VCE up to 60 V.
15	2C	output	Output 2 - open-collector Darlington output, sinks up to 500 mA continuous, VCE up to 60 V.
16	1C	output	Output 1 - open-collector Darlington output, sinks up to 500 mA continuous, VCE up to 60 V.

CAD (KiCad official)

Symbol: ULN2003AN
Footprint: Package_DIP:DIP-16_W7.62mm
3D model: DIP-16 (KiCad packages3D, STEP)
3D model files: uln2003an-etched.step / uln2003an-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); uln2003an.step / uln2003an.glb are the bare package body.
