AC244005 - 

The MPLAB REAL ICE Isolator enables connectivity to AC and High-voltage applications not referenced to ground. Control signals are magnetically or optically isolated providing up to 2.5 kV equivalent isolation protection. The isolator acts as an isolated bridge, where signals are passed through with complete transparency to the MPLAB REAL ICE or MPLAB IDE. The MPLAB REAL ICE Isolator requires Part Number AC244002, the MPLAB REAL ICE High Performance Pak with LVDS differential signaling supporting full-speed debugging. The isolator does not support the PIC10F PIC12F, PIC16F, PIC18F, PIC18FK, and dsPIC30F since they require a programming voltage on VPP.
