The MAX4614 is able to connect two of its pins, if the corresponding state pin is on high. Each IC has 4 channels for switching. In our application is a simultanious switching of all 12 wires needed. So you`ll find 3 of MAX4614 ICs on the PCB.
Now I use it to connect and disconnect my deebugger ;)
The MAX4614 promises a Rail-to-Rail Signal Handling and a max turn ON time of 15nsec.
