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 | NC1 | passive | Normally-closed terminal of SPDT switch 1. Connected to COM1 when IN1-2 = 0. Rail-to-rail analog signal path, 0V to V+, 0.6Ω typical Ron. |+| 2 | IN1-2 | input | Digital control input for SPDT switches 1 and 2. TTL/CMOS compatible: VIH ≥ 1.5V (5V supply) / 1.3V (3.3V), VIL ≤ 0.6V/0.5V. When 0, NCx connects to COMx; when 1, NOx connects to COMx. |+| 3 | NO2 | passive | Normally-open terminal of SPDT switch 2. Connected to COM2 when IN1-2 = 1. Rail-to-rail analog signal path, 0V to V+, 0.6Ω typical Ron. |+| 4 | COM2 | passive | Common terminal of SPDT switch 2. Routed to NC2 or NO2 under control of IN1-2. Bidirectional analog/digital signal, 0V to V+. |+| 5 | NC2 | passive | Normally-closed terminal of SPDT switch 2. Connected to COM2 when IN1-2 = 0. |+| 6 | GND | power_in | Ground reference for the device. All analog signals are referenced from GND up to V+. |+| 7 | NO3 | passive | Normally-open terminal of SPDT switch 3. Connected to COM3 when IN3-4 = 1. |+| 8 | COM3 | passive | Common terminal of SPDT switch 3. Routed to NC3 or NO3 under control of IN3-4. Bidirectional analog/digital signal, 0V to V+. |+| 9 | NC3 | passive | Normally-closed terminal of SPDT switch 3. Connected to COM3 when IN3-4 = 0. |+| 10 | IN3-4 | input | Digital control input for SPDT switches 3 and 4. TTL/CMOS compatible: VIH ≥ 1.5V (5V) / 1.3V (3.3V), VIL ≤ 0.6V/0.5V. When 0, NCx connects to COMx; when 1, NOx connects to COMx. |+| 11 | NO4 | passive | Normally-open terminal of SPDT switch 4. Connected to COM4 when IN3-4 = 1. |+| 12 | COM4 | passive | Common terminal of SPDT switch 4. Routed to NC4 or NO4 under control of IN3-4. Bidirectional analog/digital signal, 0V to V+. |+| 13 | NC4 | passive | Normally-closed terminal of SPDT switch 4. Connected to COM4 when IN3-4 = 0. |+| 14 | V+ | power_in | Positive supply, 1.8V to 5.5V. Sets rail-to-rail analog signal range (0 to V+). Quiescent current ≤ 1µA. |+| 15 | NO1 | passive | Normally-open terminal of SPDT switch 1. Connected to COM1 when IN1-2 = 1. |+| 16 | COM1 | passive | Common terminal of SPDT switch 1. Routed to NC1 or NO1 under control of IN1-2. Bidirectional analog/digital signal, 0V to V+. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Jiangsu RUNIC Tech |+| Package | QFN-16-EP(3x3) |+| Category | Interface |+| Pins | 16 |++## Ordering variants++- `RS2099XTQC16XTQC16`+- `RS2099XTQC16XTSS16`++## CAD (KiCad official)++- Symbol: `RS2099XTQC16`+- Footprint: `Package_DFN_QFN:QFN-16-1EP_3x3mm_P0.5mm_EP1.7x1.7mm`+- 3D model: QFN-16-EP(3x3) (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Jiangsu RUNIC Tech datasheet](docs/rs2099xtqc16-datasheet.pdf) (12 pp, sha256 `dcad3d9525dbca63`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
