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 | S2B | bidirectional | Source pin 2B. Bidirectional analog signal I/O for switch 2 (throw B). Signal range VSS to VDD. |+| 2 | S2A | bidirectional | Source pin 2A. Bidirectional analog signal I/O for switch 2 (throw A). Signal range VSS to VDD. |+| 3 | S3B | bidirectional | Source pin 3B. Bidirectional analog signal I/O for switch 3 (throw B). Signal range VSS to VDD. |+| 4 | D3 | bidirectional | Drain pin 3. Bidirectional common (pole) I/O for switch 3. Signal range VSS to VDD. |+| 5 | S3A | bidirectional | Source pin 3A. Bidirectional analog signal I/O for switch 3 (throw A). Signal range VSS to VDD. |+| 6 | EN | input | Active-low logic enable. When high, all switches are turned off. When low, the SELx inputs determine switch connections. 1.8V logic compatible, VIH up to VDD. |+| 7 | VSS | power_in | Negative power supply. Most negative supply potential (0V single-supply, down to −2.75V dual-supply). Decouple with 0.1µF-10µF to GND. Tie to GND for single-supply operation. |+| 8 | GND | power_in | Ground (0V) reference. |+| 9 | SEL3 | input | Logic control select for switch 3. Selects between S3A and S3B connection to D3 as listed in Table 8-1. 1.8V logic compatible. |+| 10 | SEL2 | input | Logic control select for switch 2. Selects between S2A and S2B connection to D2 as listed in Table 8-1. 1.8V logic compatible. |+| 11 | SEL1 | input | Logic control select for switch 1. Selects between S1A and S1B connection to D1 as listed in Table 8-1. 1.8V logic compatible. |+| 12 | S1A | bidirectional | Source pin 1A. Bidirectional analog signal I/O for switch 1 (throw A). Signal range VSS to VDD. |+| 13 | S1B | bidirectional | Source pin 1B. Bidirectional analog signal I/O for switch 1 (throw B). Signal range VSS to VDD. |+| 14 | D1 | bidirectional | Drain pin 1. Bidirectional common (pole) I/O for switch 1. Signal range VSS to VDD. |+| 15 | D2 | bidirectional | Drain pin 2. Bidirectional common (pole) I/O for switch 2. Signal range VSS to VDD. |+| 16 | VDD | power_in | Positive power supply. Most positive supply potential (1.08V-5.5V). Decouple with 0.1µF-10µF between VDD and GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | TSSOP-16 |+| Category | Interface |+| Pins | 16 |++## Ordering variants++- `TMUX1133PWRPW`+- `TMUX1133PWRPWR`+- `TMUX1133PWRPW`+- `TMUX1133PWRPWR`++## CAD (KiCad official)++- Symbol: `TMUX1133PWR`+- 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/tmux1133.pdf) (42 pp, sha256 `08082d5484460c92`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
