TCA9511ADGKR from Texas Instruments, in a VSSOP-8-0.65mm. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | EN | input | Active-high chip enable; high for normal operation with precharge and rise-time acceleration, low for shutdown mode with bus isolation and disabled accelerators. |
| 2 | SCLOUT | bidirectional | Serial clock output connected to card-side SCL bus; open-drain I2C buffer line supporting bidirectional buffering and clock stretching. |
| 3 | SCLIN | bidirectional | Serial clock input from backplane-side SCL bus; open-drain I2C buffer line supporting bidirectional buffering and clock stretching. |
| 4 | GND | power_in | Supply ground reference. |
| 5 | READY | output | Open-drain connection status flag pulled low when EN low or start-up incomplete, released high by 10 kΩ external pull-up when EN high and start-up complete. |
| 6 | SDAIN | bidirectional | Serial data input from backplane-side SDA bus; open-drain I2C buffer line supporting bidirectional buffering and clock stretching. |
| 7 | SDAOUT | bidirectional | Serial data output connected to card-side SDA bus; open-drain I2C buffer line supporting bidirectional buffering and clock stretching. |
| 8 | VCC | power_in | Supply power input with range of 2.3 V to 5.5 V; bypass with 0.1 μF capacitor placed close to pin for best results. |
