TDM 4 mode on ADAU1361: paralleling multiple devices

In the TDM4 mode, does the ADC_DATA pin on the ADAU1361 go tri-state during TDM slots in which it is not programmed to respond?

I want to parallel multiple codecs on the same serial port lines.  If the digital outputs don't go high-impedence during other slots, the outputs will conflict.

Optional bonus point question: Is there an equivalent to the ADAU1361 that will do multiple channels?  I'm looking for 4-8 channels of single-ended line input and differential line output.  SPI control is a must.
