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 | A0 | input | Address line 0. Controls the switch configuration together with A1 and A2 to select which source pin (S1-S8) is connected to D. 1.8-V logic compatible input. |+| 2 | EN | input | Active-high enable. When low, all switches are turned off (Hi-Z). When high, the A[2:0] address inputs determine which switch is turned on. 1.8-V logic compatible. |+| 3 | NC | unconnected | Not connected. Leave floating or tie as convenient; no internal connection. |+| 4 | S1 | bidirectional | Source pin 1. Analog/digital signal path pin; can be an input or output. Signal range GND to VDD; 5 Ω typical on-resistance to D when selected. |+| 5 | S2 | bidirectional | Source pin 2. Analog/digital signal path pin; can be an input or output. Signal range GND to VDD. |+| 6 | S3 | bidirectional | Source pin 3. Analog/digital signal path pin; can be an input or output. Signal range GND to VDD. |+| 7 | S4 | bidirectional | Source pin 4. Analog/digital signal path pin; can be an input or output. Signal range GND to VDD. |+| 8 | D | bidirectional | Drain (common) pin. Bidirectional analog/digital signal path pin connected to the selected source S1-S8. Signal range GND to VDD. |+| 9 | S8 | bidirectional | Source pin 8. Analog/digital signal path pin; can be an input or output. Signal range GND to VDD. |+| 10 | S7 | bidirectional | Source pin 7. Analog/digital signal path pin; can be an input or output. Signal range GND to VDD. |+| 11 | S6 | bidirectional | Source pin 6. Analog/digital signal path pin; can be an input or output. Signal range GND to VDD. |+| 12 | S5 | bidirectional | Source pin 5. Analog/digital signal path pin; can be an input or output. Signal range GND to VDD. |+| 13 | VDD | power_in | Positive power supply (1.08 V to 5.5 V). Most positive power-supply potential. Bypass with a 0.1 µF to 10 µF decoupling capacitor between VDD and GND for reliable operation. |+| 14 | GND | power_in | Ground (0 V) reference for the device. |+| 15 | A2 | input | Address line 2. Controls the switch configuration together with A0 and A1 to select which source pin (S1-S8) is connected to D. 1.8-V logic compatible input. |+| 16 | A1 | input | Address line 1. Controls the switch configuration together with A0 and A2 to select which source pin (S1-S8) is connected to D. 1.8-V logic compatible input. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | TSSOP-16 |+| Category | Global Sourcing Parts |+| Pins | 16 |++## Ordering variants++Same part, different packaging or reel option.++- `TMUX1208PWR`+- `TMUX1208PWRRSVR`+- `TMUX1208PWRRSV`++## CAD (KiCad official)++- Symbol: `TMUX1208PWR`+- 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/tmux1208.pdf) (37 pp, sha256 `c2683e83f693c8d9`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
