Typical Applications
ISO6763 is suitable for 6 applications: Isolated RS-485 Bus Nodes, CAN Bus Isolation, Isolated SPI for ADCs and DACs, Motor Drive Gate-Drive Signal Isolation, PLC I/O Modules, Automotive Body and Powertrain Isolation.
Isolated RS-485 Bus Nodes
The ISO6763 isolates the UART/control lines feeding RS-485 transceivers in industrial fieldbus nodes. Its 50 Mbps rate comfortably exceeds 20 Mbps profiling needs, and 50 kV/us CMTI sustains signaling through large ground-potential transients common on long factory floors. Six channels in 3/3 direction allow full TX/RX plus direction-control and fault signaling across one device, replacing multiple dual-channel isolators and cutting BOM count and board area.
Recommended
CAN Bus Isolation
For isolated CAN and CAN FD nodes, the ISO6763 isolates TX, RX, and standby/control signals between the MCU and CAN transceiver. Its 5000 Vrms reinforced isolation supports safety separation in industrial and automotive gateways, while 50 kV/us CMTI keeps the bus stable under load-dump and ground-shift events. The 1.8 V logic support lets it sit directly beside modern low-voltage MCUs without level translators.
Recommended
Isolated SPI for ADCs and DACs
The ISO6763's 50 Mbps data rate supports high-throughput isolated SPI links to precision data converters. Three channels in each direction carry SCLK, MOSI/CS and MISO/DRDY signals with low channel-to-channel skew across the barrier. 1.8 V to 5 V supply support on both sides allows direct connection to low-voltage converters and 5 V industrial logic. The capacitive isolation adds no switching noise into sensitive analog domains.
Recommended
Motor Drive Gate-Drive Signal Isolation
In motor inverters, the ISO6763 isolates PWM and fault/enable signals between the MCU controller domain and IGBT/SiC gate-driver domain. The 50 kV/us CMTI is essential where high dv/dt switching edges would corrupt ordinary optocouplers, and 5000 Vrms reinforced rating supports the safety separation between low-voltage control and high-voltage power stages. Low propagation delay preserves PWM dead-time accuracy for efficient switching.
Recommended
PLC I/O Modules
Programmable logic controller I/O cards use the ISO6763 to isolate digital input/output banks from the backplane logic. Six channels per device consolidate isolation for dense I/O boards, reducing component count versus dual-channel parts. Reinforced 5000 Vrms isolation addresses field-wiring surge exposure, and robust EMC performance helps meet industrial immunity requirements in electrically noisy cabinets.
Recommended
Automotive Body and Powertrain Isolation
For vehicle ECUs linking 3.3 V/5 V domains across battery-domain boundaries, the AEC-Q100 qualified ISO6763FQDWRQ1 variant provides identical 3/3-channel, 50 Mbps, 5000 Vrms isolation with automotive qualification. It suits onboard charger communication, isolated sensor interfaces, and domain gateway links. The shared package with the standard ISO6763 lets one PCB layout serve both industrial and automotive end items.

Key Differentiators
- Latest-generation reinforced EMC isolator (vs ISO7763DWR)
- Direct automotive path with same footprint (vs ISO6763FQDWRQ1)
- 1.8 V logic support on both sides (vs ADuM261N1BRZ)
Design Notes
Place 0.1 uF ceramic bypass capacitors within 2 mm of both VCC1 and VCC2 pins, each referenced to its own side ground. Maintain the isolation barrier as a continuous board slot or gap; route all six signals perpendicular to the barrier to preserve creepage and minimize inter-channel coupling across the isolation boundary.
Tie unused channel inputs to a defined logic level (VCC or GND of that side). Floating inputs on capacitive isolators can oscillate and inject noise into adjacent channels. Also confirm default output states on power-up: if the other side is unpowered, outputs default low, which matters for fail-safe behavior in RS-485 direction control and gate-drive enable lines.
At 50 Mbps, use series termination (22 to 33 ohm) on high-speed channels near the driving side to control ringing, and keep traces on each side short with solid ground references. The isolator's low channel-to-channel skew suits clocked SPI; minimize asymmetric trace lengths between clock and data lines to preserve setup/hold margins at the receiver.
Compliance Information
RoHS compliant per DigiKey listing for ISO6763DWR. AEC-Q100 qualification applies only to ISO6763FQDWRQ1 variant. Detailed REACH/halogen status: see TI quality portal.
