PCA9306IDCURQ1 from Texas Instruments, in a VSSOP-8-0.5mm. 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 | GND | power_in | Ground, 0 V reference. |
| 2 | VREF1 | power_in | Low-voltage-side reference supply voltage for SCL1 and SDA1 I/O channels. |
| 3 | SCL1 | bidirectional | Serial clock, low-voltage side; open-drain port connected to VREF1 through pullup resistor. |
| 4 | SDA1 | bidirectional | Serial data, low-voltage side; open-drain port connected to VREF1 through pullup resistor. |
| 5 | SDA2 | bidirectional | Serial data, high-voltage side; open-drain port connected to VREF2 through pullup resistor. |
| 6 | SCL2 | bidirectional | Serial clock, high-voltage side; open-drain port connected to VREF2 through pullup resistor. |
| 7 | VREF2 | power_in | High-voltage-side reference supply voltage for SCL2 and SDA2 I/O channels. |
| 8 | EN | input | Enable input; when high connects SCL1/SDA1 to SCL2/SDA2; when low isolates buses with high impedance. |
