I wish to communicate with a I2C device that uses 3V3 I2C levels. I know the USB 8451 will accept a 3V3 I2C input as a 'high' logic level, but can the USB 8451 provide a I2C output at 3V3 logic levels to the target device?
Do I need to add an external voltage level shifter IC between the USB-8451 and the target I2C device?
