ADXRS453 SPI states

Most slave devices have tri-state outputs so their MISO signal becomes high impedance (logically disconnected) when the device is not selected. Devices without tri-state outputs cannot share SPI bus segments with other devices; only one such slave could talk to the master.

Is the ADXRS453's outputs are tri-state ?

Does for communicate with 3.3v processor SPI, DVDD should be connected to 3.3v while AVDD connected to 5v (to ensure get the datasheet mentioned performance)?
