NCA9306DPH from Nexperia, in a TSSOP-8. 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). |
| 2 | refA | power_in | Low-voltage side reference supply voltage for SCLA and SDAA. |
| 3 | SCLA | bidirectional | Open-drain SCL data input/output on the A side, connected to SCLB when EN is HIGH and high-impedance when EN is LOW; requires a pull-up resistor. |
| 4 | SDAA | bidirectional | Open-drain SDA data input/output on the A side, connected to SDAB when EN is HIGH and high-impedance when EN is LOW; requires a pull-up resistor. |
| 5 | SDAB | bidirectional | Open-drain SDA data input/output on the B side, connected to SDAA when EN is HIGH and high-impedance when EN is LOW; requires a pull-up resistor. |
| 6 | SCLB | bidirectional | Open-drain SCL data input/output on the B side, connected to SCLA when EN is HIGH and high-impedance when EN is LOW; requires a pull-up resistor. |
| 7 | refB | power_in | High-voltage side reference supply voltage for SCLB and SDAB. |
| 8 | EN | input | Enable input, active HIGH; HIGH turns the translator switch on, LOW puts the channels in a high-impedance state. |
