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 | Y0 | bidirectional | Analog switch input/output Y0. Selected to Y when A=0, B=0 and ENABLE is low. Signal range 0 V to VCC; typical on-resistance 48 Ω at VCC=5 V. |+| 2 | Y2 | bidirectional | Analog switch input/output Y2. Selected to Y when A=0, B=1 and ENABLE is low. Signal range 0 V to VCC. |+| 3 | Y | bidirectional | Analog switch common terminal (‘Y’ output) for the Y-bank 4:1 mux. Connects to the selected Y0-Y3 input when ENABLE is low. |+| 4 | Y3 | bidirectional | Analog switch input/output Y3. Selected to Y when A=1, B=1 and ENABLE is low. Signal range 0 V to VCC. |+| 5 | Y1 | bidirectional | Analog switch input/output Y1. Selected to Y when A=1, B=0 and ENABLE is low. Signal range 0 V to VCC. |+| 6 | ENABLE | input | Active-low digital enable input. When low, the selected X/Y channels are turned on; when high, all switches are open. Normally tied to GND for always-on operation. VIH ≥ 1.7 V, VIL ≤ 0.5 V. |+| 7 | NC | unconnected | No internal connection. Leave floating or tie to GND. |+| 8 | GND | power_in | Ground reference for both analog and digital circuitry. Connect to system digital ground. |+| 9 | B | input | Digital address ‘B’ input (MSB of channel select). Together with A selects one of four X/Y channel pairs when ENABLE is low. VIH ≥ 1.7 V, VIL ≤ 0.5 V. |+| 10 | A | input | Digital address ‘A’ input (LSB of channel select). Together with B selects one of four X/Y channel pairs when ENABLE is low. VIH ≥ 1.7 V, VIL ≤ 0.5 V. |+| 11 | X3 | bidirectional | Analog switch input/output X3. Selected to X when A=1, B=1 and ENABLE is low. Signal range 0 V to VCC. |+| 12 | X0 | bidirectional | Analog switch input/output X0. Selected to X when A=0, B=0 and ENABLE is low. Signal range 0 V to VCC. |+| 13 | X | bidirectional | Analog switch common terminal (‘X’ output) for the X-bank 4:1 mux. Connects to the selected X0-X3 input when ENABLE is low. |+| 14 | X1 | bidirectional | Analog switch input/output X1. Selected to X when A=1, B=0 and ENABLE is low. Signal range 0 V to VCC. |+| 15 | X2 | bidirectional | Analog switch input/output X2. Selected to X when A=0, B=1 and ENABLE is low. Signal range 0 V to VCC. |+| 16 | VCC | power_in | Positive analog and digital supply voltage input. Operating range +2.5 V to +5.5 V; typical ICC = 1 µA at 5 V. Bypass to GND with a local decoupling capacitor. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Jiangsu RUNIC Tech |+| Package | SOIC-16 |+| Category | Interface |+| Pins | 16 |++## Ordering variants++Same part, different packaging or reel option.++- `RS2252XS16`+- `RS2252XSS16`+- `RS2252XTSS16`+- `RS2252XTQC16`++## CAD (KiCad official)++- Symbol: `RS2252XS16`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOIC-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Jiangsu RUNIC Tech datasheet](docs/rs2252xs16-datasheet.pdf) (13 pp, sha256 `96c3a2b26d3bb481`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
