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 | B2 | bidirectional | Input/Output 2, referenced to VCCB (B-side, 2.3V to 5.5V). Bidirectional data line paired with A2 through an internal transmission gate; supports push-pull (24 Mbps) or open-drain (2 Mbps). |+| 2 | GND | power_in | Device ground return, 0 V reference for both supplies. |+| 3 | VCCA | power_in | A-port supply voltage. Range 1.65V ≤ VCCA ≤ 3.6V, and VCCA must be ≤ VCCB. Sets the logic level for the A-side (A1, A2) and OE input. |+| 4 | A2 | bidirectional | Input/Output 2, referenced to VCCA (A-side, 1.65V to 3.6V). Bidirectional data line paired with B2 through an internal transmission gate. |+| 5 | A1 | bidirectional | Input/Output 1, referenced to VCCA (A-side, 1.65V to 3.6V). Bidirectional data line paired with B1 through an internal transmission gate. |+| 6 | OE | input | 3-state Output Enable, referenced to VCCA. Pulling OE low places all A- and B-side outputs into a high-impedance state, reducing supply current. VIH ≥ VCCA×0.65, VIL ≤ VCCA×0.35. |+| 7 | VCCB | power_in | B-port supply voltage. Range 2.3V ≤ VCCB ≤ 5.5V. Sets the logic level for the B-side (B1, B2). Includes ±8kV ESD protection on this rail. |+| 8 | B1 | bidirectional | Input/Output 1, referenced to VCCB (B-side, 2.3V to 5.5V). Bidirectional data line paired with A1 through an internal transmission gate; supports push-pull (24 Mbps) or open-drain (2 Mbps). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Union Semiconductor |+| Package | VSSOP-8-0.5mm |+| Category | Logic |+| Pins | 8 |++## Ordering variants++- `UM3202V`+- `UM3202VUM3202Q`+- `UM3202VUM3202H`++## CAD (KiCad official)++- Symbol: `UM3202V`+- Footprint: `Package_SO:VSSOP-8_2.3x2mm_P0.5mm`+- 3D model: VSSOP-8-0.5mm (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Union Semiconductor datasheet](docs/um3202v-datasheet.pdf) (15 pp, sha256 `4c291947b17a8c65`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
