TMUX1111RSVR from Texas Instruments, in a UQFN-16(1.8x2.6). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | S1 | bidirectional | Source pin 1, which can be an input or output; signal path voltage is limited to 0 V to VDD. |
| 2 | N.C. | unconnected | No internal connection. |
| 3 | GND | power_in | Ground (0 V) reference. |
| 4 | S4 | bidirectional | Source pin 4, which can be an input or output; signal path voltage is limited to 0 V to VDD. |
| 5 | D4 | bidirectional | Drain pin 4, which can be an input or output; signal path voltage is limited to 0 V to VDD. |
| 6 | SEL4 | input | Logic control input 4 sets channel 4 state as shown in Section 8.5; recommended input voltage is 0 V to 5.5 V. |
| 7 | SEL3 | input | Logic control input 3 sets channel 3 state as shown in Section 8.5; recommended input voltage is 0 V to 5.5 V. |
| 8 | D3 | bidirectional | Drain pin 3, which can be an input or output; signal path voltage is limited to 0 V to VDD. |
| 9 | S3 | bidirectional | Source pin 3, which can be an input or output; signal path voltage is limited to 0 V to VDD. |
| 10 | N.C. | unconnected | No internal connection. |
| 11 | VDD | power_in | Positive power supply, the most positive supply potential; supply range is 1.08 V to 5.5 V, with a 0.1 µF to 10 µF decoupling capacitor between VDD and GND for reliable operation. |
| 12 | S2 | bidirectional | Source pin 2, which can be an input or output; signal path voltage is limited to 0 V to VDD. |
| 13 | D2 | bidirectional | Drain pin 2, which can be an input or output; signal path voltage is limited to 0 V to VDD. |
| 14 | SEL2 | input | Logic control input 2 sets channel 2 state as shown in Section 8.5; recommended input voltage is 0 V to 5.5 V. |
| 15 | SEL1 | input | Logic control input 1 sets channel 1 state as shown in Section 8.5; recommended input voltage is 0 V to 5.5 V. |
| 16 | D1 | bidirectional | Drain pin 1, which can be an input or output; signal path voltage is limited to 0 V to VDD. |

## CAD (KiCad official)

- Symbol: `TMUX1111RSVR`
- Footprint: `Package_DFN_QFN:UQFN-16_1.8x2.6mm_P0.4mm`
- 3D model: UQFN-16(1.8x2.6), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.55 mm nominal UFQFPN height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `tmux1111rsvr-etched.step` / `tmux1111rsvr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tmux1111rsvr.step` / `tmux1111rsvr.glb` are the bare package body.
