High voltage isolation capabilities are provided using a first integrated circuit die that includes an inverting circuit path and a non-inverting circuit path coupled to receive a single-ended signal and to generate a differential signal from the single-ended signal for transmission over an isolation link. A second integrated circuit die includes a differential Schmitt trigger circuit coupled to the differential signal communicated over the isolation link and to supply at least one output signal corresponding thereto. An isolation barrier is disposed between the inverting and non-inverting circuit paths and the differential Schmitt trigger circuit and includes at least two isolation capacitors coupled to respectively transmit each portion of the differential signal.
