I'm developing a mainboard with sockets for several modules. Mainboard VCC is a 5V, modules - 3.3/5V, depends on type. Is it possibles to use ADG3308 as level converter and bus switch in following conditions?
VCCA may not be present for a long time (no module installed). EN will be at GND (mainboard will sence module voltage). Hot insertion not required. Some modules may require pullup or pulldown resistors on bus.
