ADG3304 - I2C

Is it possible to use the ADG3304 for I2C level translating (3,3V Master, 5V slave)?

    The ADG3304 is not designed to be used for I2C level translating. The device has an internal 6kohm resistor on its output which in conjunction with the pull up resistor required for I2C creates a resistor divider network. This results in difficulties in driving the desired logic level.
