RS0204YQ from Jiangsu RUNIC Tech, in a TSSOP-14. 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. 1.2 V ≤ VCCA ≤ 3.6 V and VCCA ≤ VCCB. Sets the logic level of the A-port I/Os and OE reference. |
| 2 | A1 | bidirectional | Input/output A1, referenced to VCCA. Bidirectional level-translated data line paired with B1. |
| 3 | A2 | bidirectional | Input/output A2, referenced to VCCA. Bidirectional level-translated data line paired with B2. |
| 4 | A3 | bidirectional | Input/output A3, referenced to VCCA. Bidirectional level-translated data line paired with B3. |
| 5 | A4 | bidirectional | Input/output A4, referenced to VCCA. Bidirectional level-translated data line paired with B4. |
| 6 | NC | unconnected | No internal connection. Leave floating or tie to GND. |
| 7 | GND | power_in | Ground reference for the device. |
| 8 | OE | input | Output Enable (active high), referenced to VCCA. Drive OE low to place all A/B I/Os into 3-state; has an internal pull-down current source (device requires an external pull-down to guarantee Hi-Z at power-up/down). |
| 9 | NC | unconnected | No internal connection. Leave floating or tie to GND. |
| 10 | B4 | bidirectional | Input/output B4, referenced to VCCB. Bidirectional level-translated data line paired with A4. |
| 11 | B3 | bidirectional | Input/output B3, referenced to VCCB. Bidirectional level-translated data line paired with A3. |
| 12 | B2 | bidirectional | Input/output B2, referenced to VCCB. Bidirectional level-translated data line paired with A2. |
| 13 | B1 | bidirectional | Input/output B1, referenced to VCCB. Bidirectional level-translated data line paired with A1. |
| 14 | VCCB | power_in | B-port supply voltage. 1.65 V ≤ VCCB ≤ 5.5 V. Must be ≥ VCCA. Sets the logic level of the B-port I/Os. |

Two STEP files. Same geometry, different body top:
| File | Size | Use it when |
|---|---|---|
rs0204yq.step |
194 KB | You want the bare part, or you mark your own boards. |

2.3 MB | You want the part with RS0204YQ already on it. |
The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 572 faces against 237 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
