It supports a data rate of 25 Mbps with typical rise/fall times of 2 ns and a maximum propagation delay of 42 ns in either direction. The 3/1 channel split (three inputs on side 1, one on side 2) suits asymmetric interfaces like SPI or UART where the main data flow is one way. ## Package and mounting The 2500 Vrms isolation rating is the basic safety isolation level for industrial equipment — motor drives, PLC I/O modules, and power supplies — where the isolator must prevent ground loops and protect low-voltage logic from transient voltages on the field side. The 25 kV/µs common-mode transient immunity (CMTI) means the part can reject fast voltage spikes common in inverter-driven environments without corrupting the data stream. For a 25 Mbps signal with 42 ns propagation delay, the pulse-width distortion is held to 2.5 ns maximum, keeping the duty cycle close to 50% through the isolation barrier. ## Industrial temperature range and wide-body SOIC Surface-mount assembly is standard; no isolated power is integrated, so the design must supply separate power domains on each side of the barrier. If a second-source option is needed, the ISO7241 family includes pin-compatible variants with different channel configurations — the base product number ISO7241 spans the same package and isolation rating.","metaTitle":"TI ISO7241CDW General Purpose Isolator, 25 Mbps, 2500 Vrms","metaDescription":"Texas Instruments ISO7241CDW capacitive-coupling isolator: 25 Mbps data rate, 2500 Vrms isolation, 4 unidirectional channels, 3.15V–5.5V supply, -40°C 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":"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":"$7.4200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ec48dd4d2a144297fc20727889bc3e0c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is ISO7241CDW compatible with 3.3V systems?","answer":"Yes.
