With a 1Mbps data rate and three forward channels plus one reverse channel (3/1 configuration), it is sized for isolating SPI, UART, or general-purpose logic lines in industrial fieldbus interfaces, motor drive feedback, and PLC I/O modules. The wide supply range from 3.15V to 5.5V lets it bridge 3.3V and 5V logic domains directly, eliminating a separate level translator on the BOM. ## 25kV/µs CMTI — keeps data clean in noisy environments Common-mode transient immunity is specified at a minimum 25kV/µs, which means fast-switching edges from a downstream IGBT or MOSFET stage will not glitch the isolated data path. This is the spec that matters when the isolator sits between a controller and a motor-drive power stage or an inverter phase leg. The 95ns max propagation delay (both directions) and 10ns max pulse-width distortion are tight enough for most 1Mbps synchronous serial links, but budget the full 95ns in your timing closure for the return path through the single reverse channel. The 16-SOIC wide-body package (7.50mm width) provides the creepage distance needed to maintain the 4000Vpk isolation rating across the temperature range. The rise and fall times are a typical 2ns, so the output edges are clean enough to drive a CMOS input without extra Schmitt triggering in most layouts. ## Sourcing and lifecycle posture For dual-sourcing or supply resilience, the ISO7240ADWR is a pin-compatible sibling within the same family — the difference is channel direction mapping (the ISO7240 uses a 4/0 configuration versus the 3/1 here), so verify the directional fit against your bus topology before substituting.","metaTitle":"TI ISO7241ADWR Digital Isolator, 4-Ch, 1Mbps, 4000Vpk","metaDescription":"Texas Instruments ISO7241ADWR quad-channel digital isolator with capacitive coupling, 1Mbps data rate, 4000Vpk isolation, 3.15-5.5V supply, -40 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":"Tape & Reel (TR)","Data Rate":"1Mbps","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":"3.15V ~ 5.5V","Number of Channels":"4","Base Product Number":"ISO7241","Voltage - Isolation":"4000Vpk","Operating Temperature":"-40°C~125°C","Inputs - Side 1/Side 2":"3/1","Rise / Fall Time (Typ)":"2ns, 2ns","Supplier Device Package":"16-SOIC","Pulse Width Distortion (Max)":"10ns","Propagation Delay tpLH / tpHL (Max)":"95ns, 95ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.6360","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://www.ti.com/general/docs/suppproductinfo.tsp?distId=10&gotoUrl=https%3A%2F%2Fwww.ti.com%2Flit%2Fgpn%2Fiso7240a","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between ISO7241ADWR and ISO7240ADWR?","answer":"Both are quad-channel capacitive-coupling digital isolators in the same 16-SOIC wide package with identical 4000Vpk isolation, 1Mbps data rate, and supply range. The difference is the channel direction mapping: ISO7241ADWR has three forward and one reverse channel (3/1), while ISO7240ADWR has all four channels in the forward direction (4/0).

The supply voltage range is 3.15V to 5.5V, so a 5V rail is well within the operating window. The wide range also allows mixing 3.3V on one side and 5V on the other, as long as each side's supply stays within the 3.15V to 5.5V limits."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/ISO7241ADWR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/ISO7241ADWR when reusing this data.
