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 | VCCA | power_in | A-port supply voltage. 1.65 V ≤ VCCA ≤ 5.5 V, and VCCA must be ≤ VCCB. Sets the reference rail for the A-side I/Os and the OE input. |+| 2 | A1 | bidirectional | Bidirectional level-translated I/O channel 1, A-side. Referenced to VCCA. Supports push-pull (24 Mbps) and open-drain (2 Mbps) signaling. |+| 3 | A2 | bidirectional | Bidirectional level-translated I/O channel 2, A-side. Referenced to VCCA. |+| 4 | A3 | bidirectional | Bidirectional level-translated I/O channel 3, A-side. Referenced to VCCA. |+| 5 | A4 | bidirectional | Bidirectional level-translated I/O channel 4, A-side. Referenced to VCCA. |+| 6 | NC | unconnected | No internal connection. May be left floating or tied to any potential within the abs-max range. |+| 7 | GND | power_in | Device ground reference (0 V) for both supply rails and all I/Os. |+| 8 | OE | input | Output Enable (active high), referenced to VCCA. Drive OE low (≤ VCCA × 0.25) to place all A/B I/Os in the high-impedance 3-state mode; drive high (≥ VCCA × 0.8) for normal translation. An internal pull-down current source keeps OE low while VCCA is powered; tie to GND via a pull-down resistor to guarantee Hi-Z during power up/down. |+| 9 | NC | unconnected | No internal connection. May be left floating or tied to any potential within the abs-max range. |+| 10 | B4 | bidirectional | Bidirectional level-translated I/O channel 4, B-side. Referenced to VCCB. |+| 11 | B3 | bidirectional | Bidirectional level-translated I/O channel 3, B-side. Referenced to VCCB. |+| 12 | B2 | bidirectional | Bidirectional level-translated I/O channel 2, B-side. Referenced to VCCB. |+| 13 | B1 | bidirectional | Bidirectional level-translated I/O channel 1, B-side. Referenced to VCCB. |+| 14 | VCCB | power_in | B-port supply voltage. 2.3 V ≤ VCCB ≤ 5.5 V and VCCB ≥ VCCA. Sets the reference rail for the B-side I/Os. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Jiangsu RUNIC Tech |+| Package | TSSOP-14 |+| Category | Logic |+| Pins | 14 |++## Ordering variants++- `RS0104YQYQ`+- `RS0104YQYTQF14`+- `RS0104YQYTQE12`++## CAD (KiCad official)++- Symbol: `RS0104YQ`+- Footprint: `Package_SO:TSSOP-14_4.4x5mm_P0.65mm`+- 3D model: TSSOP-14 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Jiangsu RUNIC Tech datasheet](docs/rs0104yq-datasheet.pdf) (23 pp, sha256 `b9cb7825e3455cb1`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
