It delivers 5000Vrms galvanic isolation across a 2.25V to 5.5V supply range, with a 100Mbps data rate and propagation delay of 16ns max. ## What the 5000Vrms and 85kV/µs CMTI mean for your design The 5000Vrms isolation voltage is the reinforced-grade rating for mains-connected automotive and industrial systems — it covers the 60-second hipot test required for safety certification in traction drives and on-board chargers. The 85kV/µs minimum common-mode transient immunity (CMTI) ensures the output stays clean when a fast-switching SiC or IGBT stage couples a high dv/dt across the isolation barrier. If your gate-driver interface or CAN/SPI isolation path sees >50 kV/µs edges, this part holds the data integrity without bit errors. ## Package and footprint notes Supplied in a 16-SSOP package (3.90mm body width, 0.154\" pitch), surface-mount only. The package is MSL 3 out of the bag — if the moisture barrier bag has been open past the floor-life window, a bake before reflow is required. The SSOP-16 footprint is shared with the wider ISO7741 family, so a board laid out for the SOIC-16 variant will need a different land pattern.","metaTitle":"TI ISO7741FQDBQQ1 Digital Isolator, AEC-Q100, 5000Vrms","metaDescription":"Texas Instruments ISO7741FQDBQQ1 is an automotive-grade (AEC-Q100) capacitive-coupling digital isolator with 5000Vrms isolation, 100Mbps data rate, 4","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-SSOP (0.154\\\", 3.90mm 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-SSOP","Pulse Width Distortion (Max)":"4.9ns","Propagation Delay tpLH / tpHL (Max)":"16ns, 16ns","Common Mode Transient Immunity (Min)":"85kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.9700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7ce28ebbb736e626ddb7ec0a8564eee9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is ISO7741FQDBQQ1 AEC-Q100 automotive qualified?","answer":"Yes, the ISO7741FQDBQQ1 is part of the Automotive, AEC-Q100 series, qualified for automotive applications per the AEC-Q100 stress test standard."},{"question":"What is the difference between ISO7741FQDBQQ1 and ISO7741FDW?","answer":"The key difference is the package: ISO7741FQDBQQ1 comes in a 16-SSOP package (3.90mm width), while the ISO7741FDW uses a 16-SOIC package (7.50mm width).
