The 16-SOIC wide-body package (14.00 mm width) provides the creepage distance needed for basic and reinforced isolation classes in on-board chargers, traction inverters, and BMS communication links. ## 85 kV/µs CMTI — why it matters for motor-drive feedback The 85 kV/µs minimum common-mode transient immunity is the spec that keeps the data path intact when a SiC or IGBT power stage switches at high dv/dt. In a traction inverter, the isolated gate driver's feedback path (desat detection, current sense) sees common-mode voltage swings of several hundred volts in tens of nanoseconds. If the isolator's CMTI is too low, the output toggles falsely and the controller sees a phantom fault. At 85 kV/µs the ISO7741QDWWQ1 comfortably handles the worst-case edge rates from modern wide-bandgap devices. ## Supply flexibility and channel mapping The channel configuration is 3 inputs on side 1 and 1 input on side 2, all unidirectional. That maps naturally to a three-channel SPI bus (SCK, MOSI, CS) plus one reverse-channel (MISO) for isolated sensor readback or gate-driver fault reporting. Propagation delay is 16 ns max in both directions, with pulse-width distortion held to 4.9 ns max, so the timing budget for a 25 MHz SPI link stays clean. ## Temperature grade and package for the engine bay The 16-SOIC wide-body (0.551\" body width, 14.00 mm lead span) provides the 8 mm+ creepage that reinforced isolation standards (IEC 60747-17, VDE 0884-11) require at the working voltage of a 400 V traction system. Surface-mount assembly with standard reflow profiles; no special pad layout beyond the usual isolation slot under the package. ## Lifecycle and sourcing posture It is the wide-body, automotive-grade variant of the ISO7741 family, sharing the same base functional specification as the industrial-grade ISO7741DW.","metaTitle":"TI ISO7741QDWWQ1 digital isolator, 5700Vrms, AEC-Q100","metaDescription":"Texas Instruments ISO7741QDWWQ1 general-purpose capacitive-coupling digital isolator.","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 (0.551\\\", 14.00mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"2.25V ~ 5.5V","Number of Channels":"4","Base Product Number":"ISO7741","Voltage - Isolation":"5700Vrms","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)":"85kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.1900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c7679fc5c2d880a67021df2342c45ad1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to ISO7741QDWWQ1?","answer":"For non-automotive designs the ISO7741DW is a drop-in replacement; for automotive BOMs the ISO7741QDWWQ1 is the required variant."},{"question":"What is the maximum data rate of ISO7741QDWWQ1?","answer":"The ISO7741QDWWQ1 is rated for a maximum data rate of 100 Mbps.
