A 1 ohm on-resistance and low charge injection pass audio and other analog signals cleanly, and it runs from a single 1.65 to 5.5 V rail. The switch is break-before-make, so the two throws never short. A small building block for 2:1 signal routing and channel selection.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | NO | bidirectional | Normally-open analog switch port. Connected to COM when IN is HIGH. Analog signal range 0 V to V+; on-state resistance ~0.75 Ω typ (5 V), peak 1 Ω typ. |+| 2 | GND | power_in | Ground reference for the device supply and control input. |+| 3 | NC | bidirectional | Normally-closed analog switch port. Connected to COM when IN is LOW. Analog signal range 0 V to V+; on-state resistance ~0.75 Ω typ (5 V). |+| 4 | COM | bidirectional | Common analog switch port. Routed to either NO or NC based on the IN control input. Handles ±200 mA continuous on-state switch current, ±400 mA peak. |+| 5 | V+ | power_in | Positive supply voltage, 1.65 V to 5.5 V single-supply operation. Absolute max 6.5 V. Quiescent supply current 0.1 µA max. |+| 6 | IN | input | Digital switch-select input. HIGH connects COM to NO; LOW connects COM to NC. 5-V tolerant regardless of V+; VIH ≥ 2.4 V, VIL ≤ 0.8 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | SPDT analog switch (1-of-2) |+| On-resistance | 1 ohm (typ) |+| Supply | 1.65-5.5 V |+| Signal range | 0 to V+ |+| Switching | Break-before-make |+| Control | Single logic input (IN) |+| Package | SOT-23-6 |++## Ordering variants++- `TS5A3159ADBVR (SOT-23-6, tape & reel)`+- `TS5A3159AYZPR (DSBGA-6)`++## CAD (KiCad official)++- Symbol: `Analog_Switch:TS5A3159ADBVR (KiCad official)`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (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/ts5a3159a.pdf) (31 pp, sha256 `384d4decc591a99e`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
