The 40 kV/µs common-mode transient immunity (CMTI) ensures the data link stays intact during fast-switching events from IGBT or SiC MOSFET stages — a spec that directly determines bit-error rate in noisy motor-drive environments. ## Channel count and direction — why 3/1 matters With three channels on side 1 and one on side 2, this part maps cleanly to isolated SPI (SCLK, MOSI, CS forward; MISO reverse) or to a CAN FD interface where TX, RX, and a wake signal cross the barrier. The unidirectional channel type means each channel drives in one direction only — no bidirectional data lines without external direction control.","metaTitle":"ISO7741QDWQ1 Automotive Digital Isolator, 100 Mbps","metaDescription":"TI ISO7741QDWQ1 is an AEC-Q100 quad-channel capacitive isolator with 100 Mbps data rate, 5000 Vrms isolation, and 40 kV/µs CMTI.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Mfr":"Texas Instruments","Type":"General Purpose","Series":"Automotive, AEC-Q100","Package":"Tube","Data Rate":"100Mbps","Technology":"Capacitive Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"2.25V ~ 5.5V","Number of Channels":"4","Base Product Number":"ISO7741","Voltage - Isolation":"5000Vrms","Operating Temperature":"-40°C~125°C","Inputs - Side 1/Side 2":"3/1","Rise / Fall Time (Typ)":"2.4ns, 2.4ns","Supplier Device Package":"16-SOIC","Pulse Width Distortion (Max)":"4.9ns","Propagation Delay tpLH / tpHL (Max)":"16ns, 16ns","Common Mode Transient Immunity (Min)":"40kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.5100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/66462c77420a67442fed40687c5d65c8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can ISO7741QDWQ1 replace ISO7741FDWQ1?","answer":"The ISO7741FDWQ1 is a functional variant within the same base family (ISO7741). Both share the same 16-SOIC package, pinout, isolation rating, and data rate. The difference is in the fail-safe output state on the default channel — verify the output logic state on power-up or with inputs open before substituting."},{"question":"What is the maximum data rate and isolation voltage of ISO7741QDWQ1?","answer":"The maximum data rate is 100 Mbps, and the isolation voltage is 5000 Vrms.
