SPI BUFFER Working Explanation

[jovin555]

Can anyone explain me the working of the following buffer.what is the purpose of this bufferand also the timing diagram at page 5?

Looks like this buffer is used in SPI for providing distanced communication or for stable communication.. The timing diagram says the buffer IC maximum takes 3.7 ns at 3.3V between switching the outputs, It allows you to use this IC upto 100MHz SPI rate..

Which diagram? The one to the bottom right of page 5?

Both Diagrams.Also why we have to use this buffer for SPI communication?is there any importance for bus capacitance in this?
