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 | IN | input | Digital control input. TTL/CMOS logic compatible: at 5V supply VIL max 0.5V and VIH min 1.3V; at 12V supply VIL max 1.4V and VIH min 2.3V. Selects which analog throw (NO or NC) is connected to COM. |+| 2 | V+ | power_in | Positive supply voltage input. Recommended operating range 3.0V to 16V (absolute max 17V). Supply current is 0.01μA typical. |+| 3 | GND | power_in | Ground reference (0V). Return for both the supply and the analog switch signals. |+| 4 | NC | passive | Normally Closed analog throw terminal. Connected to COM when IN=0 (logic low). Rail-to-rail analog signal range 0 to V+; on-resistance 3.6Ω typ at 12V (11Ω typ at 5V). Off-leakage 1nA max at 25°C. |+| 5 | COM | passive | Common analog terminal of the SPDT switch. Routed to either NC (when IN=0) or NO (when IN=1) with break-before-make timing. Rail-to-rail signal handling 0 to V+. |+| 6 | NO | passive | Normally Open analog throw terminal. Connected to COM when IN=1 (logic high). Rail-to-rail analog signal range 0 to V+; on-resistance 3.6Ω typ at 12V. Off-leakage 1nA max at 25°C. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | COSINE |+| Package | SOT-23-6 |+| Category | Comm/UART |+| Pins | 6 |++## Ordering variants++- `COS4561TR`++## CAD (KiCad official)++- Symbol: `COS4561TR`+- 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:** [COSINE datasheet](docs/cos4561tr-datasheet.pdf) (7 pp, sha256 `115122fd41935e8a`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
