Safe Operating Area (SOA) & Thermal Characteristics
No official SOA curve available for this digital IC. Always operate within absolute maximum ratings specified in the datasheet. Ensure adequate cooling and derate as needed.
Typical Applications
ISO6763 is suitable for 6 applications: Isolated RS-485 Bus Communication, Isolated SPI for ADCs and DACs, CAN Bus Isolation in Automotive and Industrial Networks, Motor Drive and Gate Driver Signal Isolation, Industrial PLC I/O Module Isolation, Isolated Battery Management Systems.
Isolated RS-485 Bus Communication
The ISO6763 fits isolated RS-485 nodes because its 3/3 channel configuration matches full-duplex TX/RX plus DE/RE signaling, while 50 kV/us CMTI keeps data integrity on grounds shifted by tens of volts in motor-drive environments. The isolator sits between the MCU UART and an isolated RS-485 transceiver such as the SN65HVD234 or ISO1042, with 5000 Vrms protecting the controller side from field-side surges. Its 50 Mbps capability covers PROFIBUS-class rates, and 1.8V logic support lets it interface directly with low-voltage MCUs without level translators.
Recommended
Isolated SPI for ADCs and DACs
High-precision data converters often require isolation between a noisy power domain and the controller. The ISO6763 isolates SPI clock, MOSI, MISO, and chip-select lines at 50 Mbps, preserving timing margins for converters such as the ADS131M08 (24-bit simultaneous-sampling delta-sigma ADC). Because propagation delay and channel-to-channel skew are low and matched, SPI clock rates of tens of MHz remain feasible across the 5000 Vrms barrier. The 3/3 channel count covers SCLK, SIMO, SOMI, CS, plus a busy/drdy return path in one 16-SOIC package.
Recommended
CAN Bus Isolation in Automotive and Industrial Networks
CAN networks in vehicles, chargers, and factory floors benefit from galvanic isolation to block ground loops and common-mode transients. The ISO6763, especially its ISO6763FQDWRQ1 AEC-Q100 variant, provides 5000 Vrms reinforced isolation and 50 kV/us CMTI between the CAN controller and transceivers like the TCAN1042GV or ISO1050. Six channels in 3/3 direction allow CAN TX/RX plus status or wake signals in one package. Wide-side 1.8V support eases connection to automotive microcontrollers running at reduced core logic voltages.
Recommended
Motor Drive and Gate Driver Signal Isolation
In three-phase inverter and servo drives, MCU control signals must cross a large ground-potential shift to reach gate drivers on high-side power stages. The ISO6763's 50 kV/us CMTI withstands the steep dv/dt events generated by SiC and IGBT switching, and its 50 Mbps rate supports PWM carrier frequencies well beyond 20 kHz with fine duty-cycle resolution. Channels route PWM, enable, and fault feedback across the 5000 Vrms barrier, pairing naturally with isolated gate drivers such as the UCC21710 for reinforced isolation in the power path.
Recommended
Industrial PLC I/O Module Isolation
Programmable logic controller I/O cards isolate field wiring (24V industrial signals, sensor lines) from backplane logic. The ISO6763 provides six isolated digital channels in a single 16-SOIC, reducing board area versus multiple dual-channel isolators, while 5000 Vrms reinforced isolation supports safety barriers between field and logic domains. Its 1.8V-to-5V dual-side logic support bridges legacy 5V backplanes and modern 1.8V FPGA or processor banks, and robust EMC performance helps modules pass industrial immunity testing in electrically noisy cabinets.
Recommended
Isolated Battery Management Systems
Battery management systems stack cell-monitoring ICs across high-voltage packs that can reach hundreds of volts above chassis ground. The ISO6763 isolates communication and control signals between the pack domain (hosting devices like the BQ79616 cell monitor) and the vehicle or system controller. Reinforced 5000 Vrms isolation and 50 kV/us CMTI handle contactor-switching transients and ensure functional-safety-grade separation, while six channels carry host communications, daisy-chain control, and fault flags simultaneously in one package.

Key Differentiators
- Newest-generation ISO676x isolation technology (vs ISO7763DWR)
- Automotive AEC-Q100 option in identical footprint (vs ISO6763FQDWRQ1)
- Six channels versus three (vs ISO7831DW)
Design Notes
Under and around the 16-SOIC DW package, remove all PCB copper (planes, traces) in the isolation barrier region to preserve creepage and clearance for reinforced 5000 Vrms isolation. TI's ISO676x datasheet (SLLSFK0E) reference layout shows the barrier routing practice; follow UL-relevant spacing on the final PCB stack.
Place a 0.1 uF ceramic bypass capacitor within 2 mm of each VCC pin (VCC1 and VCC2), referenced to GND1 and GND2 respectively. Do not share bypass capacitors across the barrier. Ensure each side supply stays within the datasheet operating range for the chosen logic level (1.8V, 2.5V, 3.3V, or 5V).
Tie unused inputs to a defined logic level (VCC or GND of that side); floating inputs on capacitive isolators may oscillate and increase quiescent current. When substituting ISO7763 or family parts (ISO6760/61/62), verify channel direction and default output states, since family members differ in these configurations.
