The wide supply range from 2.25V to 5.5V means it can bridge 3.3V and 5V logic domains directly, without external level translation. ## Automotive-grade isolation for harsh environments The 150°C rating is notably higher than the typical 125°C industrial isolator — that extra headroom matters when the part sits near a hot power stage or inside a sealed ECU with limited airflow. The common-mode transient immunity of 85kV/µs minimum is the spec that keeps data intact when a motor drive or DC-DC converter switches at high dv/dt. In a noisy environment, a lower CMTI part can latch or corrupt the output; this rating gives confidence that the isolation barrier holds clean through fast transients. ## Data rate and timing — what 100Mbps means for your bus At 100Mbps, this isolator handles SPI clock rates up to 50MHz (double-edge) or 100MHz single-edge, plus most fieldbus protocols like RS-485, CAN (with an external transceiver), and general-purpose GPIO isolation. The propagation delay is 16.5ns max, and pulse-width distortion stays under 4.9ns — tight enough that you won't lose timing margin on a 50MHz SPI bus, but you should still budget the delay in your setup/hold calculations. Rise and fall times are 2.4ns typical, which keeps edge rates clean without excessive ringing. ## Package and supply — design-in notes Housed in a 16-pin SOIC with 7.50mm body width, the package provides the creepage distance needed to support the 5000Vrms isolation rating. The wide supply range (2.25V to 5.5V) means you can power side 1 from a 3.3V rail and side 2 from a 5V rail, or both from the same supply — no separate regulator needed. No isolated power is generated internally; each side needs its own supply and ground reference. ## Lifecycle and sourcing The base product number is ISO7741, and the 'FEDWQ1' suffix denotes the automotive-qualified variant in the wide-body SOIC package.","metaTitle":"ISO7741FEDWQ1 Digital Isolator, 100Mbps, 5000Vrms, AEC-Q100","metaDescription":"TI ISO7741FEDWQ1 general-purpose capacitive-coupling digital isolator, 4-ch unidirectional, 100Mbps, 5000Vrms isolation, AEC-Q100 automotive qualified, -40°C","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~150°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)":"16.5ns, 16.5ns","Common Mode Transient Immunity (Min)":"85kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.5100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0563a7f0bbcaef2753823ce64dfac017.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does ISO7741FEDWQ1 meet automotive AEC-Q100 qualification?","answer":"Yes.
