CC3220MOD: CC3220MOD GPIO protection

Hi TI team,

We are already using CC3220MODSF12MOBR module in one of our project, 

So, Now We have a another requirement with 4 Digital and 3 Analog inputs and it has to be given out with wire hanging or with some connectors.

and there is more chance of human touch for these inputs.

Hence I wanted to give ESD protection and also should protect against over voltage also.

SO kindly suggest me a suitable TVS diode for Digital inputs(working voltage-3.3V) and for analog inputs(1.8V)

Thanks
