ULN2003G-S16-R from UTC Unisonic Tech, in a SOP-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 I1 input Input to Darlington channel 1. TTL/CMOS compatible; drives output O1 low when high.
2 I2 input Input to Darlington channel 2. TTL/CMOS compatible; drives output O2 low when high.
3 I3 input Input to Darlington channel 3. TTL/CMOS compatible; drives output O3 low when high.
4 I4 input Input to Darlington channel 4. TTL/CMOS compatible; drives output O4 low when high.
5 I5 input Input to Darlington channel 5. TTL/CMOS compatible; drives output O5 low when high.
6 I6 input Input to Darlington channel 6. TTL/CMOS compatible; drives output O6 low when high.
7 I7 input Input to Darlington channel 7. TTL/CMOS compatible; drives output O7 low when high.
8 GND power_in Device ground / emitter return for all Darlington pairs.
9 COM power_in Common cathode of the internal freewheel (clamp) diodes. Tie to the load supply (up to 50 V) when switching inductive loads.
10 O7 output Open-collector Darlington output channel 7. Sinks up to 500 mA to GND; V(OUT) up to 50 V off-state.
11 O6 output Open-collector Darlington output channel 6. Sinks up to 500 mA to GND; V(OUT) up to 50 V off-state.
12 O5 output Open-collector Darlington output channel 5. Sinks up to 500 mA to GND; V(OUT) up to 50 V off-state.
