P82B715DR from Texas Instruments, in a SOIC-8. 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 | NC | unconnected | No internal connection. Leave floating or tie to a convenient node; not electrically bonded inside the package. |
| 2 | Lx | bidirectional | Buffered serial data bus (LDA) side. Low-impedance bidirectional buffered SDA output driving the extended/long bus (supports up to 3000 pF, sink capability ~30 mA). Requires a pullup resistor to Vcc on this side. |
| 3 | Sx | bidirectional | Serial data bus (SDA) side. Connects to the standard I2C master/slave SDA line through a pullup resistor to Vcc; supports up to 400 pF bus capacitance on this side. |
| 4 | GND | power_in | Ground reference for the device. Connect to system ground. |
| 5 | NC | unconnected | No internal connection. Leave floating or tie to a convenient node; not electrically bonded inside the package. |
| 6 | Sy | bidirectional | Serial clock bus (SCL) side. Connects to the standard I2C master/slave SCL line through a pullup resistor to Vcc; supports up to 400 pF bus capacitance on this side. |
| 7 | Ly | bidirectional | Buffered serial clock bus (LCL) side. Low-impedance bidirectional buffered SCL output driving the extended/long bus (supports up to 3000 pF, sink capability ~30 mA). Requires a pullup resistor to Vcc on this side. |
| 8 | VCC | power_in | Supply voltage. Recommended operating range 4.5 V to 12 V (functional down to 3 V with reduced dynamic performance); absolute maximum 12 V. Bypass with a local decoupling capacitor. |

Two STEP files. Same geometry, different body top:

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 507 faces against 147 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.
