It provides three forward-direction channels (Side 1 to Side 2) and one reverse-direction channel, all unidirectional. The wide supply range from 3.15V to 5.5V lets it bridge 3.3V and 5V logic domains without a level shifter. The 4000Vpk isolation rating is the headline spec for this part. It means the ISO7241ADW can withstand a 4 kV peak transient between the two sides, which is sufficient for reinforced insulation in many industrial and medical applications. For a procurement decision, this rating determines whether the part can replace an optocoupler-based solution in a design that needs a smaller footprint and higher reliability. The capacitive coupling technology also gives it a typical common-mode transient immunity of 25kV/µs minimum, so data stays clean even when large voltage spikes slam across the isolation barrier — a common failure point in motor-drive and inverter designs. ## 1 Mbps data rate — is it fast enough? At 1 Mbps, this isolator handles standard UART, SPI (at moderate clock rates), and general-purpose GPIO isolation. It is not intended for high-speed protocols like USB 2.0 or gigabit Ethernet. The propagation delay is 95 ns max (both directions), and pulse-width distortion is 10 ns max. For a typical 1 MHz clock, that delay is about 10% of the period — fine for most control and sensor interfaces, but check timing margins if you are daisy-chaining multiple isolators or running near the rate limit. ## Package and mounting notes It is surface-mount only. The wide body gives better creepage distance for high-voltage applications compared to the narrow SOIC-16. No exposed thermal pad, so standard reflow profiles for SOIC-16W apply. ## Lifecycle and sourcing posture That means no last-time-buy risk for current production designs. For dual-sourcing resilience, the ISO7241 family includes other channel-count variants (ISO7240, ISO7242) that share the same base technology and package, but pin compatibility should be verified against the datasheet.","metaTitle":"ISO7241ADW Digital Isolator, 4000Vpk, 1 Mbps, 16-SOIC","metaDescription":"Texas Instruments ISO7241ADW general-purpose capacitive coupling isolator, 4-ch unidirectional, 4000Vpk isolation, 1 Mbps data rate, -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":"16-SOIC (0.295\\\", 7.50mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 5.5V","Number of Channels":"4","Base Product Number":"ISO7241","Voltage - Isolation":"4000Vpk","Operating Temperature":"-40°C~125°C","Inputs - Side 1/Side 2":"3/1","Rise / Fall Time (Typ)":"2ns, 2ns","Supplier Device Package":"16-SOIC","Pulse Width Distortion (Max)":"10ns","Propagation Delay tpLH / tpHL (Max)":"95ns, 95ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.9000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://www.ti.com/general/docs/suppproductinfo.tsp?distId=10&gotoUrl=https%3A%2F%2Fwww.ti.com%2Flit%2Fgpn%2Fiso7240a","sourceUrl":null},"ai":{"faq":[{"question":"What is the data rate of ISO7241ADW?","answer":"The ISO7241ADW supports a data rate of 1 Mbps."},{"question":"What package does ISO7241ADW come in?","answer":"It comes in a 16-pin SOIC wide-body package (16-SOIC, 7.50 mm width), surface-mount."},{"question":"Is ISO7241ADW a capacitive coupling isolator?","answer":"Yes, it uses capacitive coupling technology."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/ISO7241ADW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/ISO7241ADW when reusing this data.
