The 50 Mbps line rate is enough for CAN FD, SPI, and UART links running at typical automotive bus speeds — you get clean signal edges with 2.6 ns typical rise/fall time and 18 ns max propagation delay per channel. The 3000 Vrms isolation rating covers the galvanic barrier requirements for traction inverter, BMS, and on-board charger communication interfaces where the system must survive a 60-second hi-pot test. The 100 kV/µs minimum common-mode transient immunity (CMTI) means the outputs won't glitch when a motor drive or DC-DC converter switches at high dV/dt — a common failure point in hybrid/electric vehicle power stages.","metaTitle":"TI ISO6721RBQDRQ1 Automotive Isolator, 50 Mbps, 3000 Vrms","metaDescription":"Texas Instruments ISO6721RBQDRQ1 automotive general-purpose capacitive coupling isolator. 50 Mbps data rate, 3000 Vrms isolation, AEC-Q100, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":"Functional Safety (FuSa)","packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Grade":"Automotive","Series":"Functional Safety (FuSa)","Package":"Tape & Reel (TR); Cut Tape (CT)","Data Rate":"50Mbps","Technology":"Capacitive Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Qualification":"AEC-Q100","Isolated Power":"No","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"1.71V ~ 1.89V, 2.25V ~ 5.5V","Number of Channels":"2","Voltage - Isolation":"3000Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"1/1","Rise / Fall Time (Typ)":"2.6ns, 2.6ns","Supplier Device Package":"8-SOIC","Pulse Width Distortion (Max)":"7ns","Propagation Delay tpLH / tpHL (Max)":"18ns, 18ns","Common Mode Transient Immunity (Min)":"100kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.72","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.72000","currency":"USD"},{"qty":10,"price":"$1.54700","currency":"USD"},{"qty":25,"price":"$1.45960","currency":"USD"},{"qty":100,"price":"$1.24350","currency":"USD"},{"qty":250,"price":"$1.16756","currency":"USD"},{"qty":500,"price":"$1.02162","currency":"USD"},{"qty":1000,"price":"$0.84648","currency":"USD"},{"qty":3000,"price":"$0.71584","currency":"USD"},{"qty":6000,"price":"$0.68933","currency":"USD"},{"qty":15000,"price":"$0.66281","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2b556be4da421b5dfc62540453e9e95d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum data rate of ISO6721RBQDRQ1?","answer":"The ISO6721RBQDRQ1 supports a maximum data rate of 50 Mbps, with 2.6 ns typical rise/fall times and 18 ns max propagation delay, sufficient for CAN FD, SPI, and UART links."},{"question":"How does ISO6721RBQDRQ1 compare to ISO6742FQDWRQ1?","answer":"The ISO6742FQDWRQ1 is a four-channel version (2 inputs on side 1, 2 on side 2) in the same 8-SOIC package, sharing the same 50 Mbps data rate, 3000 Vrms isolation, and 100 kV/µs CMTI.
