Question about LTC2360


I have a question about the following description written in the LTC2360 data sheet page 18.

Regarding the description using three-state buffers to isolate the ADC data buswhich of the signals, SDO, CONV and SCK, needs an external three-state buffer?

I think all of them dont need a three state buffer since SDO is Hi-Z during conversion and CONV and SCK are input.

Is my understanding of that incorrect?
