CISSOID at NAC Semi · Isolated Transceivers
RHEA Dual-Channel Isolated Transceiver
CHT-RHEA integrates two transmit and two receive channels for full-duplex digital communication across an isolation barrier. Each digital signal uses an external pulse transformer; a complete four-line link requires one RHEA IC on each side.
RHEA carries control and feedback signals in the HADES isolated gate-driver technology. On-off keying modulation, configurable modulation frequency and transmit/receive enable controls support operation in high-temperature systems.
