... These devices feature a negative signal capability that allows signals as low as V 5.5V to pass through without distortion. The MAX4744/MAX4745 feature two digital control bits to control each switch independently (see Table 1). The MAX4744H/MAX4745H/MAX4746H have one control bit to switch both switches and an enable input EN to put the switches in a high-impedance mode ...

... Typical Operating Characteristics ). The switches are bidi- rectional, so the NO_, NC_, and COM_ terminals can be used as either inputs or outputs. COM_ Protection with V (MAX4744H/MAX4745H/MAX4746H) This feature prevents any damage to the device due to improper power-supply sequencing. The protection applies if a signal is applied on COM_ when V than 0 ...
