The 475 ns max propagation delay (tpLH/tpHL) and 14 ns max pulse-width distortion mean it handles asynchronous signalling without skew-induced errors, but it will not support full-speed SPI at 10 MHz or CAN FD — that is where the sibling ISO7220ADRG3 (25 Mbps) steps in. ## 25 kV/µs CMTI and the industrial noise floor In a factory-automation PLC or a servo drive, that rating keeps the data path from glitching on the rising edge of a 600 V bus. The 1 ns typical rise/fall time is fast enough for clean edge detection but not so fast that it radiates — the slew rate is inherently limited by the 1 Mbps ceiling.","metaTitle":"TI ISO7220ADRG4 General Purpose Digital Isolator, 1 Mbps","metaDescription":"Texas Instruments ISO7220ADRG4 dual-channel digital isolator, 1 Mbps data rate, 2500 Vrms isolation, capacitive coupling, -40°C to 125°C, 8-SOIC.","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":"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":"ISO7220","Voltage - Isolation":"2500Vrms","Operating Temperature":"-40°C~125°C","Inputs - Side 1/Side 2":"2/0","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":"$4.1300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1712d03fe062b8dd6fd316c327e8b1ca.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ISO7220ADRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between ISO7220ADRG4 and ISO7220ADRG3?","answer":"The primary difference is data rate: the ISO7220ADRG4 is rated for 1 Mbps, while the ISO7220ADRG3 supports 25 Mbps. Both share the same 8-SOIC package, 2500 Vrms isolation, capacitive coupling, and 3V to 5.5V supply range. If your design needs faster SPI or CAN isolation, the ADRG3 is the pin-compatible upgrade; for UART or low-speed GPIO, the ADRG4 is sufficient and may carry a cost advantage."},{"question":"Is ISO7220ADRG4 RoHS compliant?","answer":"Yes, the ISO7220ADRG4 is RoHS compliant.
