The enable input G can be used todisable the device so that the busses areeffectively isolated.All inputs and outputs are equipped with protec-tion circuits against static discharge, giving them2KV ESD immunity and transient excess voltage.All floating bus terminals during High Z State mustbe held HIGH or LOW.
