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.
