Is 5V I2C/SPI voltage allowed on the SC18IS602B IC?

I have a question about the SC18IS602B I2C to SPI bridge. I know the supply is 3.3V but it mentions in the datasheet that the pins are 5V tolerant.

Could you use this chip with 5V I2C and SPI buses?

Hello Tom,

To be able to use the SC18IS602B with MCUs that use 5V logic level on their communication lines, a proper level-translation circuit should be used.

Best regards,

Tomas
