The unidirectional channel type means you plan the signal flow before laying out the board: anything that needs to come back across the barrier needs a separate isolator or a part with side-2 inputs. ## 1Mbps data rate and 475ns propagation delay — timing budget for control loops At 1Mbps the ISO7220ADR handles SPI clock rates up to 1 MHz, UART at 115200 baud with margin, and general-purpose GPIO isolation for slow-to-moderate-speed signals. The 475ns max propagation delay (tpLH / tpHL) adds just under a microsecond of latency through the barrier — fine for most sensor readouts and status feedback, but worth checking against a fast fault latch or a current-regulation loop that expects an answer inside 200 ns. ## 25kV/µs CMTI — why this part suits motor drives and inverter environments Fast-switching SiC or IGBT bridges generate voltage transients that can couple across the isolation barrier and corrupt data or trigger false edges. A 25kV/µs floor means the ISO7220ADR holds its output state through the dv/dt events typical in 400V-class motor drives, solar inverters, and industrial power supplies. The capacitive coupling technology inherently handles these transients better than optocouplers at equivalent speed, which is why this part is a common choice for isolating gate-driver feedback and fault signals. ## Supply range 3V to 5.5V — single-rail or split-rail flexibility The ISO7220ADR operates from 3V to 5.5V on both sides, so it works with 3.3V logic on the controller side and 5V logic on the field side without a level translator. The 8-SOIC package (0.154\" width, 3.90mm body) is a standard footprint that routes easily on two-layer boards. The full temperature range applies to both the supply voltage window and the isolation rating — no derating of the 2500Vrms barrier at high temperature, which is a common gotcha with some optocoupler-based isolators. This makes the part suitable for outdoor telecom cabinets, factory-floor sensors near hot machinery, and engine-bay electronics that see thermal cycling. For BOM planning, the base product number ISO7220 covers multiple package and tape options, so the ADR suffix (SOIC-8 in tape-and-reel) is the standard surface-mount variant for volume assembly.","metaTitle":"TI ISO7220ADR Digital Isolator, 2Ch, 1Mbps, 2500Vrms, SOIC-8","metaDescription":"Texas Instruments ISO7220ADR dual-channel digital isolator with capacitive coupling, 1Mbps data rate, 2500Vrms isolation, -40°C to 125°C range.","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); Cut Tape (CT)","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)","Product Status":"Active","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":"$3.0200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1712d03fe062b8dd6fd316c327e8b1ca.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ISO7220ADR/alternatives.json"},"ai":{"faq":[{"question":"Is ISO7220ADR compatible with 3.3V logic?","answer":"Yes.
