ADG918 Blocking of high amplitude signals

I'm planning to use the ADG918 for multiplexing between two inputs. The ON path shall pass signals up to +/-0.5Vp which is nicely within the 7 dBm max. input spec. The OFF port may, however, be subjected to 20-40 ns spikes of up to +/-2Vp. My concern is that a negative spike may turn on the blocking NFET and "leak" through to the RFC port. What will happen? (I'm not using DC-biasing)
