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 | SEL1 | input | Logic control input 1 selecting switch 1. TTL/CMOS-compatible (VIH/VIL referenced to VDD). Logic 1 turns switch 1 on (TMUX6112 is normally open). |+| 2 | D1 | bidirectional | Drain pin 1 of SPST switch 1. Can be an input or output (analog signal path, rail-to-rail from VSS to VDD). |+| 3 | S1 | bidirectional | Source pin 1 of SPST switch 1. Can be an input or output (analog signal path, rail-to-rail from VSS to VDD). |+| 4 | VSS | power_in | Negative power supply, most-negative supply potential. Can be tied to GND for single-supply operation (10V to 17V VDD). Decouple with 0.1µF to 10µF between VSS and GND. |+| 5 | GND | power_in | Ground (0V) reference for digital logic thresholds. |+| 6 | S4 | bidirectional | Source pin 4 of SPST switch 4. Can be an input or output (analog signal path, rail-to-rail from VSS to VDD). |+| 7 | D4 | bidirectional | Drain pin 4 of SPST switch 4. Can be an input or output (analog signal path, rail-to-rail from VSS to VDD). |+| 8 | SEL4 | input | Logic control input 4 selecting switch 4. TTL/CMOS-compatible. Logic 1 turns switch 4 on (normally open). |+| 9 | SEL3 | input | Logic control input 3 selecting switch 3. TTL/CMOS-compatible. Logic 1 turns switch 3 on (normally open). |+| 10 | D3 | bidirectional | Drain pin 3 of SPST switch 3. Can be an input or output (analog signal path, rail-to-rail from VSS to VDD). |+| 11 | S3 | bidirectional | Source pin 3 of SPST switch 3. Can be an input or output (analog signal path, rail-to-rail from VSS to VDD). |+| 12 | NC | unconnected | No internal connection. Leave floating or tie to any convenient net. |+| 13 | VDD | power_in | Positive power supply, most-positive supply potential. Operating range 10V to 17V (single supply) or ±5V to ±17V (dual supply, VDD-VSS ≤ 34V). Decouple with 0.1µF to 10µF between VDD and GND. |+| 14 | S2 | bidirectional | Source pin 2 of SPST switch 2. Can be an input or output (analog signal path, rail-to-rail from VSS to VDD). |+| 15 | D2 | bidirectional | Drain pin 2 of SPST switch 2. Can be an input or output (analog signal path, rail-to-rail from VSS to VDD). |+| 16 | SEL2 | input | Logic control input 2 selecting switch 2. TTL/CMOS-compatible. Logic 1 turns switch 2 on (normally open). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | TSSOP-16 |+| Category | Interface |+| Pins | 16 |++## Ordering variants++- `TMUX6112PWR`+- `TMUX6112PWRRTER`+- `TMUX6112PWRRTE`++## CAD (KiCad official)++- Symbol: `TMUX6112PWR`+- Footprint: `Package_SO:TSSOP-16_4.4x5mm_P0.65mm`+- 3D model: TSSOP-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tmux6112.pdf) (37 pp, sha256 `ed9a4ce8b7b85e75`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
