At 25 Mbps, this isolator handles common serial protocols like SPI, UART, and GPIO isolation. The 42 ns max propagation delay is symmetrical, and the 2.5 ns pulse-width distortion preserves duty cycle for most PWM and encoder signals. ## 25 kV/µs CMTI — why it matters for motor drives and inverters Common-mode transient immunity (CMTI) of 25 kV/µs (minimum) is the spec that determines whether the isolator maintains data integrity when fast-switching voltages slam across the isolation barrier. In a motor-drive or inverter application where IGBT/SiC FETs switch at tens of kV/µs, a lower CMTI part would corrupt the output data. This rating means the ISO7240CDW can be used in industrial drives, solar inverters, and EV chargers without adding external filtering to suppress barrier noise. The wide-body SOIC-16 package provides 8 mm creepage distance, which helps meet IEC 60950-1 reinforced insulation requirements for mains-connected equipment. It is ROHS3 compliant. No direct second-source alternate is listed, but the wide supply range and standard pinout mean it can be cross-referenced against other 4-channel, unidirectional capacitive-coupling isolators in the same package if dual-sourcing is required.","metaTitle":"ISO7240CDW Digital Isolator, 2500Vrms, 25Mbps, 16-SOIC","metaDescription":"Texas Instruments ISO7240CDW general-purpose digital isolator with 2500Vrms isolation, 25Mbps data rate, 4 unidirectional channels, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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":"ISO7240","Voltage - Isolation":"2500Vrms","Operating Temperature":"-40°C~125°C","Inputs - Side 1/Side 2":"4/0","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":"$8.5000","priceTiers":[{"qty":1,"price":"$8.50000","currency":"USD"},{"qty":10,"price":"$7.67800","currency":"USD"},{"qty":25,"price":"$7.32080","currency":"USD"},{"qty":100,"price":"$6.35660","currency":"USD"},{"qty":250,"price":"$6.07092","currency":"USD"},{"qty":500,"price":"$5.53526","currency":"USD"},{"qty":1000,"price":"$5.05350","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ec48dd4d2a144297fc20727889bc3e0c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ISO7240CDW/alternatives.json"},"ai":{"faq":[{"question":"What is the data rate of ISO7240CDW?","answer":"The ISO7240CDW supports a maximum data rate of 25 Mbps, with a typical rise/fall time of 2 ns and a maximum propagation delay of 42 ns."},{"question":"Is ISO7240CDW compatible with 3.3V logic?","answer":"Yes."},{"question":"What is the recommended replacement for ISO7240CDW?","answer":"No official replacement has been announced since the part remains active.
