Its headline rating is 5700Vrms of isolation, which provides reinforced insulation for industrial drives, medical patient-contact equipment, and grid-tied power converters where a fault must not propagate across the isolation barrier. The 100Mbps data rate handles SPI clock lines, UART signals, and general-purpose GPIO isolation without timing margin issues — the 25ns propagation delay (max) and 4.5ns pulse-width distortion are tight enough for most synchronous interfaces. ## 100kV/µs CMTI — why it matters for motor drives and inverters Common-mode transient immunity is rated at 100kV/µs minimum. In a variable-frequency drive, the switching node of the IGBT can slew at tens of kV/µs; a lower CMTI isolator would glitch or latch, corrupting the gate-drive or feedback signal. This part holds the data path clean through those edges, which is the difference between a reliable inverter and one that sporadically faults. ## Supply range and logic compatibility The supply range spans 2.25V to 5.5V on both sides, so it works directly with 3.3V or 5V logic without external level shifters. The unidirectional channel configuration — 2 inputs on side 1, 0 on side 2 — means it is a fixed-direction isolator; ideal for isolating sensor outputs or control signals that flow one way, not for bidirectional buses like I²C. ## Temperature grade and deployment The 16-SOIC wide-body package (7.50mm width) provides the creepage distance needed to maintain the 5700Vrms rating across the board.","metaTitle":"ISO7820LLDW Digital Isolator, 5700Vrms, 100Mbps, 16-SOIC","metaDescription":"TI ISO7820LLDW general-purpose digital isolator: 5700Vrms isolation, 100Mbps data rate, capacitive coupling, -55°C to 125°C.","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","Supplier Device Package":"16-SOIC","Pulse Width Distortion (Max)":"4.5ns","Propagation Delay tpLH / tpHL (Max)":"25ns, 25ns","Common Mode Transient Immunity (Min)":"100kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.77","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$9.77000","currency":"USD"},{"qty":10,"price":"$8.82900","currency":"USD"},{"qty":40,"price":"$8.41875","currency":"USD"},{"qty":120,"price":"$7.30983","currency":"USD"},{"qty":280,"price":"$6.98132","currency":"USD"},{"qty":520,"price":"$6.36533","currency":"USD"},{"qty":1000,"price":"$5.54399","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/af49fa7a0cf27dce805dddb2c9fdf3ea.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is ISO7820LLDW suitable for SPI isolation?","answer":"Yes, the 100Mbps data rate and 25ns propagation delay are sufficient for SPI clock rates up to 50 MHz, though the unidirectional channel count (2 inputs side 1, 0 side 2) means you need one device per direction for full-duplex SPI."},{"question":"What is the common mode transient immunity of ISO7820LLDW?","answer":"The minimum common-mode transient immunity is 100kV/µs, which handles the fast voltage transients in motor-drive and inverter environments without data corruption."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/ISO7820LLDW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/ISO7820LLDW when reusing this data.
