We have a requirement to access 20 USB devices in a PCB placed in a thermal chamber(operating Temperature @ 125C) using single USB host.We could not find any 1X20 Mux/Demux that can operate @ 125C. We could find 1x2 channel switch @ 125C.We would like to know if this switch can be used to access all the 20 devices by cascading the Switches as shown in the attached diagram. Will the shown architecture works fine? or is there any solution available with NXP for this requirement? Kindly suggest.
