It belongs to the ISO676x-Q1 series qualified to AEC-Q100, making it a fit for automotive powertrain, battery management, and motor-drive systems where galvanic isolation between the controller and high-voltage domain is mandatory. Three channels run each direction — Side 1 gets three inputs, Side 2 gets three — which maps neatly to a standard SPI bus (SCK, MOSI, CS) plus a few GPIO or interrupt lines. ## 100 kV/µs CMTI — the number that matters in an inverter Common-mode transient immunity is rated at a minimum 100 kV/µs. That is the spec that keeps the data path from glitching when a SiC or IGBT switch transitions at several thousand volts per microsecond on the other side of the isolation barrier. In a traction inverter or an on-board charger, a weaker CMTI number means bit errors on the SPI bus during switching events — this part is specced to avoid that. ## Propagation delay and pulse-width distortion — timing budget for the SPI clock Maximum propagation delay is 18 ns in both directions, with pulse-width distortion capped at 7 ns. Rise and fall times are 4.5 ns typical. For a 50 Mbps SPI bus running at 25 MHz clock, that 18 ns eats into the setup-and-hold window on the far side — budget it when you close timing, especially across temperature. The 7 ns PWD means the high and low pulses stay reasonably symmetric, which helps keep the duty cycle distortion under control. No isolated power is built in — you supply the secondary-side rail separately, which is the usual approach for SPI isolators where the bus master and slave each have their own local regulator. ## Package and temperature — wide-body SOIC for creepage, 125°C for under-hood Surface-mount only — the wide SOIC is hand-solderable with a fine tip and some patience, but a hot-air station or reflow profile is the reliable path. ## Lifecycle and sourcing It is ROHS3 compliant.","metaTitle":"TI ISO6763FQDWRQ1 SPI Isolator, 50 Mbps, 5000 Vrms, AEC-Q100","metaDescription":"Texas Instruments ISO6763FQDWRQ1 automotive SPI digital isolator: 50 Mbps data rate, 5000 Vrms isolation, 100 kV/µs CMTI, -40°C to 125°C.
