At 1 Mbps the ISO7221ADG4 handles UART, SPI, and CAN protocols. The 475 ns max propagation delay adds about one bit-time of latency at 1 Mbps. The 25 kV/µs minimum CMTI keeps the output clean during fast motor-drive switching. No isolated power is generated on-chip — each side needs its own supply rail, which is standard for digital isolators in this class.","metaTitle":"TI ISO7221ADG4 Digital Isolator, 1 Mbps, 2500 Vrms, 8-SOIC","metaDescription":"Texas Instruments ISO7221ADG4 dual-channel digital isolator with capacitive coupling, 1 Mbps data rate, 2500 Vrms 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":"Tube","Data Rate":"1Mbps","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":"3V ~ 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)":"14ns","Propagation Delay tpLH / tpHL (Max)":"475ns, 475ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1712d03fe062b8dd6fd316c327e8b1ca.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ISO7221ADG4/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/ISO7221ADG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/ISO7221ADG4 when reusing this data.
