... Rev 1; 12/08 General Description The MAX4708/MAX4709 8-to-1 and dual 4-to-1 fault-pro- tected multiplexers are pin compatible with the industry- standard DG508/DG509. The MAX4708/MAX4709 are similar to the MAX4508/MAX4509, but these devices do not have clamp diodes to the supply rails on the switch outputs. These multiplexers feature fault-protected inputs, rail-to-rail signal-handling capability, and do not require power-supply sequencing ...

... FETs for lower on-resistance and improved flat- ness. Second, older devices limited the range of signal amplitudes the switch could pass by as much as 3V below the supply rails. The MAX4708/MAX4709 feature rail-to-rail signal handling that allows the devices to transmit signals with amplitudes at or slightly beyond the supply rails ...

... The logic-level translators convert the logic-level inputs to V+ and V- to drive the gates of the internal FETs. In this design, there is no galvanic connection inside the MAX4708/MAX4709 between the analog signal paths and GND. ESD-protection diodes connect and V-. Supply Current Reduction ...
