ADG1606 Shorted when try to tie one of the input channel with Vss

Recently I found an issue with ADG1606 Mux Chip we are using, in the layout I tied pin4 (S16) with pin 27 (Vss),  one as input and the other as the low voltage reference.  When I try to apply 5 volt on pin 6 (S14), there is short in the chip and the current goes very high.  I solve the problem by isolating the pin4 from pin27, but could anyone explain a bit more detail about why there is a short when these 2 pins tie together?


Thanks ahead.
