In a motor-drive or inverter stage where IGBT or SiC switching edges slam the local ground plane, that CMTI rating means the isolator won't falsely toggle its output when the common-mode voltage jumps. The 2.4 ns typical rise/fall time keeps the output edges clean enough to avoid excessive EMI on the secondary side. Each side of the isolation barrier can be powered independently from 2.25 V up to 5.5 V. No isolated power converter is integrated — the ISO7741DW is a signal isolator only, so each side needs its own supply rail. ## Temperature grade: full military range The wide-body SOIC package helps with creepage distance for the 5000Vrms rating at the high end of that range. ## Package and rework considerations The 16-SOIC wide-body (7.50 mm body width, 1.27 mm pitch) is a friendly package for hand rework.","metaTitle":"ISO7741DW Digital Isolator, 5000Vrms, 100Mbps, 16-SOIC","metaDescription":"TI ISO7741DW general-purpose capacitive-coupling digital isolator, 4-ch unidirectional, 5000Vrms isolation, 100Mbps data rate, -55 to 125°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":"-","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":"-55°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":"$4.3500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4823b6e05bd363491c04665aa8e36ed1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is ISO7741DW compatible with 5V systems?","answer":"Yes. The supply range of 2.25 V to 5.5 V on each side means it works directly with 5 V logic on either or both sides of the isolation barrier.

The ISO7740 and ISO7742 variants differ in channel count and direction — the ISO7741DW has three forward and one reverse channel, which is the most common configuration for isolating SPI buses (SCLK, MOSI, CS forward; MISO reverse)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/ISO7741DW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/ISO7741DW when reusing this data.
