Six-channel isolator that consolidates mixed-protocol isolation
The TI ISO6763FDWR is a general-purpose six-channel reinforced digital isolator from the ISO676x family, using capacitive coupling to pass signals across a galvanic barrier rated at 5000 Vrms. Its 50 Mbps data rate and unidirectional channel configuration (three inputs on side 1, three on side 2) make it a single-device replacement for optocoupler arrays or multi-chip isolation solutions in designs that mix CAN, RS-485, RS-232, and SPI buses on the same board.
50 kV/µs CMTI — why it matters for inverter-fed designs
With a minimum common-mode transient immunity of 50 kV/µs, this isolator maintains data integrity across the barrier when exposed to the fast voltage edges from SiC or GaN switching stages. In motor-drive or grid-tied inverter applications where the ground plane jumps several hundred volts in nanoseconds, that CMTI rating is what prevents bit errors or latch-up. The 18 ns max propagation delay (both directions) and 7 ns max pulse-width distortion keep timing margins tight enough for SPI clock rates up to 50 Mbps.
The automotive-grade variant ISO6763QDWRQ1 (AEC-Q100 qualified, 100 kV/µs CMTI) is a drop-in alternative if the application requires formal automotive qualification.
