TPNLAS4599DTT1G from TECH PUBLIC, in a SOT-23-6. 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	IN	input	Channel select logic input. Logic 0 (≤0.8V) connects COM to NC; logic 1 (≥2.4V) connects COM to NO. 1.8V logic compatible.
2	V+	power_in	Positive supply voltage input. Operating range 2V to 5.5V; absolute max 6.5V.
3	GND	power_in	Ground reference (0 V).
4	NC	bidirectional	Normally-closed analog switch terminal (independent input or output). Connected to COM when IN = logic 0. Signal range -0.3V to 5.5V; continuous current ±128mA.
5	COM	bidirectional	Common analog switch pole (output or input). Routed to either NC or NO depending on the IN select input.
6	NO	bidirectional	Normally-open analog switch terminal (independent input or output). Connected to COM when IN = logic 1. Signal range -0.3V to 5.5V; continuous current ±128mA.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tpnlas4599dtt1g.step`	97 KB	You want the bare part, or you mark your own boards.
`tpnlas4599dtt1g-etched.step`	2.3 MB	You want the part with `TPNLAS4599DTT1G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 587 faces against 117 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.
