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 | IN1 | input | Select pin for switch 1. Digital control input (5-V tolerant) chooses between the NC1 and NO1 signal paths to COM1. VIH = V+ × 0.7, VIL = V+ × 0.3. |+| 2 | NO1 | bidirectional | Normally open analog I/O for switch 1. Connected to COM1 when IN1 selects the NO path; signals pass bidirectionally through the ~10-Ω on-resistance path. |+| 3 | GND | power_in | Ground reference for the device. All analog and digital voltages are referenced to this pin. |+| 4 | NO2 | bidirectional | Normally open analog I/O for switch 2. Connected to COM2 when IN2 selects the NO path; signals pass bidirectionally through the ~10-Ω on-resistance path. |+| 5 | IN2 | input | Select pin for switch 2. Digital control input (5-V tolerant) chooses between the NC2 and NO2 signal paths to COM2. VIH = V+ × 0.7, VIL = V+ × 0.3. |+| 6 | COM2 | bidirectional | Common analog I/O for switch 2. Routed to either NC2 or NO2 depending on the state of IN2. |+| 7 | NC2 | bidirectional | Normally closed analog I/O for switch 2. Connected to COM2 when IN2 is low; signals pass bidirectionally through the ~10-Ω on-resistance path. |+| 8 | V+ | power_in | Positive supply pin. Recommended operating range 1.65 V to 5.5 V; absolute maximum 6.5 V. Bypass locally to GND with a small ceramic capacitor. |+| 9 | NC1 | bidirectional | Normally closed analog I/O for switch 1. Connected to COM1 when IN1 is low; signals pass bidirectionally through the ~10-Ω on-resistance path. |+| 10 | COM1 | bidirectional | Common analog I/O for switch 1. Routed to either NC1 or NO1 depending on the state of IN1. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | MSOP-10 |+| Category | Interface |+| Pins | 10 |++## Ordering variants++Same part, different packaging or reel option.++- `TS5A23157DGSR`+- `TS5A23157DGSRRSE`+- `TS5A23157DGSRRSER`++## CAD (KiCad official)++- Symbol: `TS5A23157DGSR`+- Footprint: `Package_SO:MSOP-10_3x3mm_P0.5mm`+- 3D model: MSOP-10 (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/ts5a23157dgsr.pdf) (30 pp, sha256 `9664b6b58ae3aef5`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
