It supports multiple serial protocols including CAN, RS232, RS485, and SPI, making it a versatile isolation solution for industrial communication interfaces. Key characteristics include a 50 Mbps data rate, 5000 Vrms isolation voltage, and 50 kV/µs common-mode transient immunity. ## 50 Mbps data rate and 18 ns propagation delay — timing margin for SPI and CAN The 50 Mbps data rate, combined with a maximum propagation delay of 18 ns (tpLH / tpHL) and pulse-width distortion of 7 ns, gives enough timing margin for most SPI, CAN, and RS-485 links up to 50 Mbps. The 4.5 ns typical rise/fall time keeps signal integrity clean on the 16-SOIC footprint. For a 50 Mbps SPI clock, the 18 ns delay adds about one clock period of latency — budget that in your read-back timing if you are polling status registers across the barrier. ## 5000 Vrms reinforced isolation and 50 kV/µs CMTI — survives motor-drive transients The 5000 Vrms isolation rating provides reinforced isolation for industrial equipment requiring safety isolation per IEC 60747-5-5. The 50 kV/µs common-mode transient immunity means this isolator will not glitch when a motor drive or inverter switches 600 V in a few nanoseconds — a common failure point for optocouplers and older capacitive isolators. The capacitive coupling technology inherently handles these fast edges better than opto-based solutions. ## Channel configuration: 3 inputs on side 1, 3 inputs on side 2 The six channels are split 3/3 — three inputs on side 1 and three inputs on side 2 — all unidirectional. This means three channels run from the primary-side supply to the secondary, and three run the opposite direction. That matches the signal flow of a typical SPI isolator (SCLK, MOSI, CS from master to slave; MISO from slave to master) plus one extra channel each way for a reset or enable signal. The ISO6763QDWRQ1 automotive-grade variant (AEC-Q100 qualified, 100 kV/µs CMTI) is a separate order code for designs requiring automotive qualification.","metaTitle":"TI ISO6763DWR 6-ch digital isolator, 50 Mbps, 5000 Vrms","metaDescription":"TI ISO6763DWR six-channel unidirectional digital isolator. 50 Mbps data rate, 5000 Vrms isolation, 50 kV/µs CMTI, -40°C to 125°C.

Both parts share the same 50 Mbps data rate, 5000 Vrms isolation, 18 ns propagation delay, and 16-SOIC package. The choice depends on whether your application needs bidirectional isolation (ISO6763) or all signals flowing one way (ISO6760)."},{"question":"Can ISO6763DWR be used for SPI isolation?","answer":"Yes. The six unidirectional channels with a 3/3 split are well suited for SPI isolation: three channels from master to slave (SCLK, MOSI, CS) and three from slave to master (MISO plus two spare for interrupt or reset signals). The 50 Mbps data rate supports SPI clock speeds up to 50 MHz, and the 18 ns propagation delay is within the timing budget for most SPI peripherals."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/ISO6763DWR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/ISO6763DWR when reusing this data.
