Leakage on ADG732

I am using ADG732 as a de-mux on a couple of my projects. in an open socket condition, when I force current I notice a leakage on the input pins even though I should be hitting the programmed clamp. By forcing different current values (positive and negative), it seems like I am reading the esd diodes on the part. Per the spec sheet my understanding is to see leakage in nA range but I significant amount of leakage. When I remove the part, I start hitting the clamps as expected. Any ideas to debug this?
