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 of the Y multiplexer. Bidirectional analog signal path; on-channel when ENABLE=0 and address B/A=00. |+| 2 | Y2 | bidirectional | Analog switch input/output Y2 of the Y multiplexer. Bidirectional analog signal path; on-channel when ENABLE=0 and B/A=10. |+| 3 | Y | bidirectional | Common terminal of the Y multiplexer. Connects to the selected Y0..Y3 channel when enabled; input and output are interchangeable. |+| 4 | Y3 | bidirectional | Analog switch input/output Y3 of the Y multiplexer. Bidirectional analog signal path; on-channel when ENABLE=0 and B/A=11. |+| 5 | Y1 | bidirectional | Analog switch input/output Y1 of the Y multiplexer. Bidirectional analog signal path; on-channel when ENABLE=0 and B/A=01. |+| 6 | ENABLE | input | Active-low digital enable input (ENABLE̅). When low the addressed channel is on; when high all switches are off. Threshold V_IH=1.7 V min, V_IL=0.5 V max. Normally connected to GND if unused. |+| 7 | NC | unconnected | No connect. Leave floating or tie to any convenient potential. |+| 8 | GND | power_in | Ground reference for both analog and digital sections. Connect to system digital ground. |+| 9 | B | input | Digital address input B (MSB of channel select). Along with A selects which of X0/Y0..X3/Y3 pairs is on when ENABLE=0. V_IH=1.7 V min, V_IL=0.5 V max. |+| 10 | A | input | Digital address input A (LSB of channel select). Along with B selects which of X0/Y0..X3/Y3 pairs is on when ENABLE=0. V_IH=1.7 V min, V_IL=0.5 V max. |+| 11 | X3 | bidirectional | Analog switch input/output X3 of the X multiplexer. Bidirectional analog signal path; on-channel when ENABLE=0 and B/A=11. |+| 12 | X0 | bidirectional | Analog switch input/output X0 of the X multiplexer. Bidirectional analog signal path; on-channel when ENABLE=0 and B/A=00. |+| 13 | X | bidirectional | Common terminal of the X multiplexer. Connects to the selected X0..X3 channel when enabled; input and output are interchangeable. |+| 14 | X1 | bidirectional | Analog switch input/output X1 of the X multiplexer. Bidirectional analog signal path; on-channel when ENABLE=0 and B/A=01. |+| 15 | X2 | bidirectional | Analog switch input/output X2 of the X multiplexer. Bidirectional analog signal path; on-channel when ENABLE=0 and B/A=10. |+| 16 | VCC | power_in | Positive analog and digital supply. Operating range 2.5 V to 5.5 V, absolute max 6 V (to GND). Typical I_CC ≈ 1 µA at 3.3 V, 2 µA max at 5 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Jiangsu RUNIC Tech |+| Package | TSSOP-16 |+| Category | Interface |+| Pins | 16 |++## Ordering variants++- `RS2252XTSS16XTSS16`+- `RS2252XTSS16XS16`+- `RS2252XTSS16XSS16`+- `RS2252XTSS16XTQC16`++## CAD (KiCad official)++- Symbol: `RS2252XTSS16`+- Footprint: `Package_SO:TSSOP-16_4.4x5mm_P0.65mm`+- 3D model: TSSOP-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Jiangsu RUNIC Tech datasheet](docs/rs2252xtss16-datasheet.pdf) (13 pp, sha256 `4973678ce4a281e5`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
