ESD protection on IIC and SPI lines

Other Parts Discussed in Thread: P82B96, TXB0104, SN74AVC4T774, TXS0104E

Hi,

 I am looking at ways to protect an interface between two systems located a short distance
from each other. I have a SPI interface, a IIC interface and a number of GPIO signals going
going between the two system. I found a TI solution for the IIC (P82B96) but now I am looking
for a solution for the SPI interface. I would like to have a buffer that has the ESD protection built in
rather than just a ESD protection device. This is so that if something happens it would be the buffer
that get destroyed not the FPGA behind it.
Any suggetions?

Thanks,

Jacob
