TS3A24159DGSR-TP from TECH PUBLIC, in a MSOP-10L. 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	VCC	power_in	Positive supply voltage. Operating range 1.5V to 5.5V; absolute maximum -0.3V to +6.5V. Quiescent current typically <2µA.
2	NO1	passive	Channel 1 normally-open analog/digital signal port. Connected to COM1 when IN1 = 1. Signal range -0.3V to 5.5V; continuous current ±100mA (peak ±200mA).
3	COM1	passive	Channel 1 common data terminal. Connects to NC1 (IN1=0) or NO1 (IN1=1) per SEL logic. Ron typ 1Ω; -3dB BW ~300MHz.
4	IN1	input	Digital control input for channel 1 selecting COM1→NO1 or COM1→NC1. VIH ≥1.6V (VCC 3.3-5.5V) or ≥1.4V (VCC 1.5-3.3V); VIL ≤0.6V/0.4V respectively. 1.8V logic compatible.
5	NC1	passive	Channel 1 normally-closed analog/digital signal port. Connected to COM1 when IN1 = 0. Signal range -0.3V to 5.5V; continuous current ±100mA.
6	GND	power_in	Ground reference for supply and logic.
7	NC2	passive	Channel 2 normally-closed analog/digital signal port. Connected to COM2 when IN2 = 0. Signal range -0.3V to 5.5V; continuous current ±100mA.
8	IN2	input	Digital control input for channel 2 selecting COM2→NO2 or COM2→NC2. Same logic thresholds as IN1; 1.8V logic compatible.
9	COM2	passive	Channel 2 common data terminal. Connects to NC2 (IN2=0) or NO2 (IN2=1) per SEL logic. Ron typ 1Ω; -3dB BW ~300MHz.
10	NO2	passive	Channel 2 normally-open analog/digital signal port. Connected to COM2 when IN2 = 1. Signal range -0.3V to 5.5V; continuous current ±100mA.

CAD (KiCad official)

3D model: MSOP-10L (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ts3a24159dgsr-tp.step`	148 KB	You want the bare part, or you mark your own boards.
`ts3a24159dgsr-tp-etched.step`	3.2 MB	You want the part with `TS3A24159DGSR-TP` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 779 faces against 177 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
