It supports a 100Mbps data rate with 16ns max propagation delay and 2.4ns typical rise/fall times, making it suitable for isolating SPI, UART, or general-purpose digital signals in systems where galvanic isolation is required for safety or noise immunity. ## 100kV/µs CMTI — what it buys you in motor drives and inverters Common-mode transient immunity is rated at a minimum of 100kV/µs. In practice, that means the isolator will not glitch or lose data when a fast voltage transient (like a 600V IGBT switching edge) slams the ground reference on one side of the barrier. For motor-drive, solar-inverter, or industrial-PLC designs where the isolated side sees high dv/dt, this CMTI rating is the spec that keeps the data path clean without external filtering. ## Two forward-only channels — plan your signal direction The channel configuration is 2 inputs on side 1, 0 inputs on side 2 — both channels carry data from side 1 to side 2 only. There is no reverse-direction channel. If your application requires bidirectional communication (e.g., a half-duplex RS-485 bus with direction control), you will need a second isolator or a part with at least one reverse channel. For purely forward paths like isolated sensor readout or SPI clock-and-data, this fixed direction is exactly what you want. ## Active lifecycle — no near-term LTB risk There is no announced last-time-buy or end-of-life notice. It is also ROHS3 compliant, so no conflict with current environmental directives.","metaTitle":"TI ISO7820FDW Digital Isolator, 5700Vrms, 100Mbps, 16-SOIC","metaDescription":"Texas Instruments ISO7820FDW general-purpose digital isolator: 5700Vrms isolation, 100Mbps data rate, 2 unidirectional channels, -55°C to 125°C, 16-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","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)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.25V ~ 5.5V","Number of Channels":"2","Voltage - Isolation":"5700Vrms","Operating Temperature":"-55°C ~ 125°C","Inputs - Side 1/Side 2":"2/0","Rise / Fall Time (Typ)":"2.4ns, 2.4ns","Supplier Device Package":"16-SOIC","Pulse Width Distortion (Max)":"4.6ns","Propagation Delay tpLH / tpHL (Max)":"16ns, 16ns","Common Mode Transient Immunity (Min)":"100kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.44","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.44000","currency":"USD"},{"qty":10,"price":"$5.81600","currency":"USD"},{"qty":25,"price":"$5.54560","currency":"USD"},{"qty":100,"price":"$4.81510","currency":"USD"},{"qty":250,"price":"$4.59872","currency":"USD"},{"qty":500,"price":"$4.19294","currency":"USD"},{"qty":1000,"price":"$3.82800","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/99fa81a569a32947f97e4ae2a0d06b08.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does ISO7820FDW work with 3.3V power supply?","answer":"Yes, the supply voltage range is 2.25V to 5.5V, so it operates on both 3.3V and 5V rails without issue."},{"question":"What is the maximum data rate of ISO7820FDW?","answer":"The maximum data rate is 100Mbps, with a typical rise/fall time of 2.4ns and a maximum propagation delay of 16ns."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/ISO7820FDW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/ISO7820FDW when reusing this data.
