PCA9306DCUT from Texas Instruments, in a VSSOP-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 | GND | power_in | Ground, 0V reference bias point for the device |
| 2 | VREF1 | power_in | Low-voltage reference supply input for SCL1 and SDA1, operating range 1.2V to (VREF2 - 0.6V) |
| 3 | SCL1 | bidirectional | Serial clock line on low-voltage side, open-drain I/O supporting 0V to 5.5V with internal clamping diode |
| 4 | SDA1 | bidirectional | Serial data line on low-voltage side, open-drain I/O supporting 0V to 5.5V with internal clamping diode |
| 5 | SDA2 | bidirectional | Serial data line on high-voltage side, open-drain I/O supporting 0V to 5.5V with internal clamping diode |
| 6 | SCL2 | bidirectional | Serial clock line on high-voltage side, open-drain I/O supporting 0V to 5.5V with internal clamping diode |
| 7 | VREF2 | power_in | High-voltage reference supply input for SCL2 and SDA2, operating range (VREF1 + 0.6V) to 5.5V |
| 8 | EN | input | Enable input for translation control; logic high enables bidirectional switching between sides with 3.5Ω ON-state resistance, logic low disables all I/O to high impedance |
