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 | Select input pin. TTL/CMOS compatible logic input that chooses which source terminal (S1x or S2x) is connected to the corresponding drain (Dx). VIH ≥ 2V, VIL ≤ 0.6V. |+| 2 | S1A | bidirectional | Source terminal 1 of channel A. Bidirectional analog I/O connected to drain DA when IN=0 and EN=0. |+| 3 | S2A | bidirectional | Source terminal 2 of channel A. Bidirectional analog I/O connected to drain DA when IN=1 and EN=0. |+| 4 | DA | bidirectional | Drain terminal (common pole) of channel A. Bidirectional analog I/O routed to either S1A or S2A per the function table. |+| 5 | S1B | bidirectional | Source terminal 1 of channel B. Bidirectional analog I/O connected to drain DB when IN=0 and EN=0. |+| 6 | S2B | bidirectional | Source terminal 2 of channel B. Bidirectional analog I/O connected to drain DB when IN=1 and EN=0. |+| 7 | DB | bidirectional | Drain terminal (common pole) of channel B. Bidirectional analog I/O routed to either S1B or S2B per the function table. |+| 8 | GND | power_in | Ground reference for the device. Connect to system ground. |+| 9 | DC | bidirectional | Drain terminal (common pole) of channel C. Bidirectional analog I/O routed to either S1C or S2C per the function table. |+| 10 | S2C | bidirectional | Source terminal 2 of channel C. Bidirectional analog I/O connected to drain DC when IN=1 and EN=0. |+| 11 | S1C | bidirectional | Source terminal 1 of channel C. Bidirectional analog I/O connected to drain DC when IN=0 and EN=0. |+| 12 | DD | bidirectional | Drain terminal (common pole) of channel D. Bidirectional analog I/O routed to either S1D or S2D per the function table. |+| 13 | S2D | bidirectional | Source terminal 2 of channel D. Bidirectional analog I/O connected to drain DD when IN=1 and EN=0. |+| 14 | S1D | bidirectional | Source terminal 1 of channel D. Bidirectional analog I/O connected to drain DD when IN=0 and EN=0. |+| 15 | ~EN | input | Active-low digital enable input (TTL/CMOS). When EN=0 all four channels operate per the IN select; when EN=1 all channels are disabled (high-impedance). |+| 16 | V+ | power_in | Positive single-supply input. Operating range 2.7V to 5.5V; absolute max 6V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | SGMICRO |+| Package | SOIC-16 |+| Category | Comm/UART |+| Pins | 16 |++## Ordering variants++Same part, different packaging or reel option.++- `SGM330A-YSYTS/TR`+- `SGM330A-YS/TR`+- `SGM330A-YSYQS/TR`++## CAD (KiCad official)++- Symbol: `SGM330A-YS`+- 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:** [SGMICRO datasheet](docs/sgm330a-ys-datasheet.pdf) (13 pp, sha256 `f631d3af6f20744f`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
