100 Mbps, 6-channel unidirectional isolator for CAN FD and SPI
The Texas Instruments ISO7762FQDWRQ1 is a six-channel, unidirectional digital isolator built with capacitive coupling technology, rated for 100 Mbps data rate and 5000 Vrms isolation. The propagation delay is a symmetric 16 ns max on both tpLH and tpHL, with pulse-width distortion held to 4.9 ns max, so the timing budget for a 1 Mbps CAN FD frame has plenty of margin.
5000 Vrms reinforced isolation, 85 kV/µs CMTI
The 5000 Vrms isolation rating qualifies for reinforced isolation per IEC 60747-5-5, suitable for motor drives, EV chargers, and industrial power supplies where galvanic separation is a safety requirement. Common-mode transient immunity is a minimum 85 kV/µs, which means the outputs won't glitch when a switching node slams several kilovolts per microsecond across the isolation barrier — a real concern in SiC and GaN inverter stages. The supply range spans 2.25 V to 5.5 V on each side independently, so you can run the controller side at 3.3 V and the bus side at 5 V without a level shifter.
AEC-Q100 qualified, -40 to 125°C operation
The rise and fall times are 1.1 ns and 1.4 ns typical — fast enough for 100 Mbps signaling but not so aggressive that the edge rate causes excessive EMI on a two-layer board. No isolated power is integrated; you supply Vcc on both sides separately.
