TS5V330CPWR from Texas Instruments, in a TSSOP-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	IN	input	Select input. Controls which S port (S1 or S2) is connected to the D port when the switch is enabled. With EN low: IN low selects S1, IN high selects S2. TTL / 5-V or 3.3-V CMOS compatible.
2	S1A	bidirectional	Channel A analog video I/O, port S1. Connects to DA when EN=L and IN=L. Bidirectional analog signal 0 V to VCC, rON typ 3 Ω.
3	S2A	bidirectional	Channel A analog video I/O, port S2. Connects to DA when EN=L and IN=H. Bidirectional analog signal 0 V to VCC.
4	DA	bidirectional	Channel A common analog video I/O (D port). Routed to S1A or S2A depending on IN; high-Z when EN=H.
5	S1B	bidirectional	Channel B analog video I/O, port S1. Connects to DB when EN=L and IN=L.
6	S2B	bidirectional	Channel B analog video I/O, port S2. Connects to DB when EN=L and IN=H.
7	DB	bidirectional	Channel B common analog video I/O (D port). Routed to S1B or S2B depending on IN; high-Z when EN=H.
8	GND	power_in	Ground reference (0 V) for the device.
9	DC	bidirectional	Channel C common analog video I/O (D port). Routed to S1C or S2C depending on IN; high-Z when EN=H.
10	S2C	bidirectional	Channel C analog video I/O, port S2. Connects to DC when EN=L and IN=H.
11	S1C	bidirectional	Channel C analog video I/O, port S1. Connects to DC when EN=L and IN=L.
12	DD	bidirectional	Channel D common analog video I/O (D port). Routed to S1D or S2D depending on IN; high-Z when EN=H.
13	S2D	bidirectional	Channel D analog video I/O, port S2. Connects to DD when EN=L and IN=H.
14	S1D	bidirectional	Channel D analog video I/O, port S1. Connects to DD when EN=L and IN=L.
15	EN	input	Active-low switch enable input (overbar EN). EN=L enables the switches (D connects to the selected S per IN); EN=H disables all switches and D/S ports become high-impedance. Should be tied to VCC via a pullup to guarantee high-Z during power up/down.
16	VCC	power_in	Positive supply voltage input. Operating range 4.5 V to 5.5 V. Static supply current ICC max 3 µA.

3D model: TSSOP-16 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ts5v330cpwr.step`	205 KB	You want the bare part, or you mark your own boards.
`ts5v330cpwr-etched.step`	2.9 MB	You want the part with `TS5V330CPWR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 696 faces against 255 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.
