It delivers 2500 Vrms isolation in a 16-SOIC wide-body package, with three channels on side 1 and one reversed channel on side 2 — a 3/1 unidirectional configuration that suits split-supply interfaces where the main data flow is one direction and a single feedback or enable line runs the other way. At 25 Mbps the ISO7241CDWR handles most fieldbus interfaces (CAN, RS-485 at 1–10 Mbps), SPI at moderate clock rates, and general-purpose GPIO isolation. The 42 ns max propagation delay in either direction (tpLH / tpHL) adds about 84 ns round-trip for a handshake signal — budget that into your timing closure if the loop goes through the isolator twice. The 2.5 ns max pulse-width distortion keeps the mark-space ratio close to 50 %, which matters for PWM signals or clock recovery where duty-cycle accuracy affects the downstream logic. ## Isolation specs that drive the BOM decision The 2500 Vrms isolation rating is the reinforced-safety figure for mains-isolated circuits in industrial PSUs, motor drives, and medical equipment where the barrier must withstand a 60-second hipot test. The 25 kV/µs minimum common-mode transient immunity (CMTI) is the spec that separates a reliable design from one that glitches on every IGBT switching edge — in a motor-drive inverter with 600 V bus voltage and 50 ns rise times, the dV/dt across the barrier can easily exceed 10 kV/µs, and the ISO7241CDWR's 25 kV/µs floor gives real margin.","metaTitle":"ISO7241CDWR General Purpose Isolator, 25 Mbps, 2500 Vrms","metaDescription":"Texas Instruments ISO7241CDWR quad-channel capacitive isolator: 25 Mbps data rate, 2500 Vrms isolation, 3.15-5.5 V 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); Cut Tape (CT)","Data Rate":"25Mbps","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":"2500Vrms","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)":"2.5ns","Propagation Delay tpLH / tpHL (Max)":"42ns, 42ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.4400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ec48dd4d2a144297fc20727889bc3e0c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the isolation specifications for ISO7241CDWR?","answer":"The ISO7241CDWR provides 2500 Vrms galvanic isolation using capacitive coupling, with a minimum common-mode transient immunity of 25 kV/µs. Propagation delay is 42 ns max in both directions, and pulse-width distortion is 2.5 ns max."},{"question":"Can ISO7241CDWR be used in 3.3V systems?","answer":"Yes. The supply voltage range is 3.15 V to 5.5 V on each side, so the part works directly in 3.3 V logic domains without a separate level translator. The 3/1 unidirectional channel count means three channels drive from side 1 to side 2, and one channel drives from side 2 back to side 1."},{"question":"What is the closest pin-compatible alternative to ISO7241CDWR in this component family?","answer":"Within the same base product family (ISO7241), the 'M' variant (ISO7241M) offers a higher data rate. For a different channel configuration, the ISO7240 series provides a 4/0 unidirectional layout (all four channels in the same direction). All share the same 16-SOIC wide-body footprint, so a PCB layout can accommodate either with a BOM change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/ISO7241CDWR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/ISO7241CDWR when reusing this data.
