Hello

The SCL,SDA and INTpin are connect to MCU that operate in 3V.

It is ok to connect those pin with pull up to 3V? In the data sheet wrote that those pin is 3.3V LVCMOS tolerant.

Hi Roy,
This should be ok. You can select a pull up resistor closer to 2K ohm. Normally we recommend 2K to 5K ohm.

Thanks,

Regarding the SN75DP159, the VCC is 3.3V.

It is ok to connect SCL_CTL, SDA_CTL,SDA_SRC, SCL_SRC with pull up resistor to 3V ?
