Is it guaranteed “Safe” to Remove or Insert a module containing the PI7C7300ANA device from a powered up “live” system?
The PI7C7300ANA is “hot-swap friendly”, which essentially means it can interface to a hot-swap power controller. But by itself cannot withstand Vcc=0V and live signals at the I/O pins — in this mode, current will flow through our bridge. Therefore, if ever there is a possibility of this happening, we require a hot-swap power controller and switches for isolation. If you do not need to pre-charge your switched signals, then the less costly PI5C32X245 or PI3C32X245 switches are appropriate for the signal switches. Most of our customers use this switch in their applications.
