SN74AVC4T234: PCB land pattern and stencil recommendations

Part Number: SN74AVC4T234

Hi Team,

    My customer got the PCN mentioned that  SN74AVC4T234ZSUR will be EOL and recommended SN74AVC4T234ZWAR (new) for it. 

   From the PCN that mentioned that nFBGA provides the same X and Y dimensions as MicroStar BGA, and provides pin-to-pin and footprint compatibility. However the nFBGA PCB land pattern and stencil recommendations have been updated to achieve better soldering results after extensive testing and evaluation.

   Here need your help to provide the PCB land pattern comparison table between SN74AVC4T234ZWAR and SN74AVC4T234ZSUE due to I can't find what the major difference from current datasheet. 

Best regards,

Albert Lee.
