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 | S4 | bidirectional | Source pin 4. Analog/digital signal path that can be an input or output. Bidirectional, rail-to-rail from GND to VDD. |+| 2 | S6 | bidirectional | Source pin 6. Analog/digital signal path that can be an input or output. Bidirectional, rail-to-rail from GND to VDD. |+| 3 | D | bidirectional | Drain pin (common). Shared analog/digital signal path that can be an input or output; connects to one of S0-S7 selected by A[2:0] when EN is low. |+| 4 | S7 | bidirectional | Source pin 7. Analog/digital signal path that can be an input or output. Bidirectional, rail-to-rail from GND to VDD. |+| 5 | S5 | bidirectional | Source pin 5. Analog/digital signal path that can be an input or output. Bidirectional, rail-to-rail from GND to VDD. |+| 6 | EN | input | Active-low enable logic input. When high, all switches are turned off. When low, the A[2:0] address inputs determine which switch is turned on. 1.8 V logic compatible; fail-safe logic allows voltage before VDD is applied. |+| 7 | NC | unconnected | Not internally connected. May be left floating or tied to any potential. |+| 8 | GND | power_in | Ground (0 V) reference. |+| 9 | A2 | input | Address line 2 (MSB). Controls the switch configuration selecting one of S0-S7 as listed in the truth table. 1.8 V logic compatible. |+| 10 | A1 | input | Address line 1. Controls the switch configuration selecting one of S0-S7 as listed in the truth table. 1.8 V logic compatible. |+| 11 | A0 | input | Address line 0 (LSB). Controls the switch configuration selecting one of S0-S7 as listed in the truth table. 1.8 V logic compatible. |+| 12 | S3 | bidirectional | Source pin 3. Analog/digital signal path that can be an input or output. Bidirectional, rail-to-rail from GND to VDD. |+| 13 | S0 | bidirectional | Source pin 0. Analog/digital signal path that can be an input or output. Bidirectional, rail-to-rail from GND to VDD. |+| 14 | S1 | bidirectional | Source pin 1. Analog/digital signal path that can be an input or output. Bidirectional, rail-to-rail from GND to VDD. |+| 15 | S2 | bidirectional | Source pin 2. Analog/digital signal path that can be an input or output. Bidirectional, rail-to-rail from GND to VDD. |+| 16 | VDD | power_in | Positive power supply, 1.62 V to 5.5 V. Most positive supply potential. Connect a 0.1 uF to 10 uF decoupling capacitor between VDD and GND for reliable operation. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | TSSOP-16-175mil |+| Category | Comm/UART |+| Pins | 16 |++## Ordering variants++- `TMUX1308PWRPWR`+- `TMUX1308PWRPW`+- `TMUX1308PWRDYYR`+- `TMUX1308PWRDYY`+- `TMUX1308PWRBQBR`+- `TMUX1308PWRBQB`++## CAD (KiCad official)++- Symbol: `TMUX1308PWR`+- Footprint: `Package_SO:TSSOP-16_4.4x5mm_P0.65mm`+- 3D model: TSSOP-16-175mil (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/tmux1308.pdf) (46 pp, sha256 `9a123a5f68937572`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
