The maximum propagation delay of 42 ns (tpLH/tpHL) and pulse-width distortion of 2 ns keep skew tight enough for synchronous links. Rise and fall times are a typical 1 ns, so the signal integrity at the receiver end is clean even across a long bus. ## 2500Vrms isolation and 25 kV/µs CMTI — where it fits Rated for 2500Vrms, it suits basic isolation in industrial automation, motor drives, and isolated data-acquisition systems. The 25 kV/µs common-mode transient immunity means it holds up in inverter and switching power-supply environments where high dV/dt edges would otherwise corrupt the data path. No isolated power is provided on-chip — the secondary side needs its own supply rail.","metaTitle":"TI ISO7221CDRG4 digital isolator, 25Mbps, 2500Vrms, 8-SOIC","metaDescription":"Texas Instruments ISO7221CDRG4 dual-channel digital isolator with capacitive coupling, 25Mbps data rate, 2500Vrms isolation, -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":"Tape & Reel (TR)","Data Rate":"25Mbps","Technology":"Capacitive Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.8V ~ 5.5V","Number of Channels":"2","Base Product Number":"ISO7221","Voltage - Isolation":"2500Vrms","Operating Temperature":"-40°C~125°C","Inputs - Side 1/Side 2":"1/1","Rise / Fall Time (Typ)":"1ns, 1ns","Supplier Device Package":"8-SOIC","Pulse Width Distortion (Max)":"2ns","Propagation Delay tpLH / tpHL (Max)":"42ns, 42ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1712d03fe062b8dd6fd316c327e8b1ca.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ISO7221CDRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the data rate of ISO7221CDRG4?","answer":"The device supports a maximum data rate of 25 Mbps, with a maximum propagation delay of 42 ns and pulse-width distortion of 2 ns."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/ISO7221CDRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/ISO7221CDRG4 when reusing this data.
