It is designed to pass digital signals at data rates up to 1Mbps while withstanding 4000Vpk isolation voltage, making it a fit for breaking ground loops in industrial control interfaces, PLC I/O modules, motor drive feedback paths, and isolated SPI or UART links. The supply range from 3.15V to 5.5V lets it operate on either a 3.3V or 5V logic rail without an external level translator. The 4000Vpk isolation rating covers reinforced-grade separation for equipment connected to mains or motor-drive power stages. The 25kV/µs minimum common-mode transient immunity ensures the output does not glitch when a fast voltage transient jumps across the isolation barrier — a common failure mode in inverter-driven environments. Combined with a 95ns max propagation delay and 10ns pulse-width distortion, this part preserves signal timing within a few tens of nanoseconds, which is sufficient for most 1Mbps serial links but not for high-speed parallel buses. ## Channel assignment and unidirectional flow The four channels are configured as three inputs on side 1 and one input on side 2, all unidirectional. This fixed direction suits applications like isolated SPI where the clock, MOSI, and chip-select travel from the controller to the peripheral (three channels) and MISO returns (one channel). It does not support bidirectional data lines such as I²C SDA without external direction control. ## Temperature grade and package It comes in a 16-SOIC wide-body package (7.50mm width), which provides the creepage distance needed to sustain the 4000Vpk isolation rating across the PCB. The Tape & Reel (TR) packaging is the standard shipping form for automated pick-and-place assembly. ## Lifecycle and sourcing posture For dual-sourcing resilience, the base product number ISO7241 covers multiple speed and package variants within the same family — verify pin compatibility with the specific suffix when qualifying an alternate.","metaTitle":"TI ISO7241ADWRG4 Digital Isolator, 4-Ch, 1Mbps, 4000Vpk","metaDescription":"Texas Instruments ISO7241ADWRG4 general-purpose digital isolator: 4 unidirectional channels, 1Mbps data rate, 4000Vpk 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":"1Mbps","Technology":"Capacitive Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","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":"$58.8000","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":"Does ISO7241ADWRG4 support bidirectional communication?","answer":"No. The ISO7241ADWRG4 has unidirectional channel types with a fixed 3/1 input-side assignment.
