Input Signal Levels for AD9286-500EBZ

Hi all,

 

I'm trying to do SPI control for the AD9286 High speed ADC using an Arduino Uno and Labview. The outputs from the Arduino Uno are 5V for logic high and 0 for Logic Low. I saw while reviewing the schematic of AD9286-500 BZ (UG191.pdf) that the buffer NC7W716 is used for level translation. Referring to this ICs data sheet I found that the input for this IC can be upto a maximum of 5.5V. So, following this, can I connect the Arduino's Outputs to the SPI control pins in the Evaluation board ?

 

I'm asking this because in the UG191 document I did not find any references to absolute maximum logic input levels.

 

Thank you
