This means the device provides both signal isolation and an isolated output supply rail from a single 20-SOIC package — no separate isolated power module needed on the board. Rated for 5000 Vrms isolation with a minimum common-mode transient immunity of 85 kV/µs, it handles the noise environment of automotive motor drives, on-board chargers, and high-voltage battery monitoring without corrupting the data stream. ## 100 Mbps data rate and propagation delay budget Maximum propagation delay is 15.7 ns in both directions; pulse-width distortion is 5 ns max. The 3/1 input-to-output channel configuration suits asymmetric data links like isolated SPI or CAN FD. ## Dual-supply range and power rail flexibility The integrated isolated power output tracks the input-side supply; decouple with a ceramic capacitor on each supply pin close to the package. Surface-mount in the 20-SOIC (7.50 mm width) package, MSL 3.","metaTitle":"ISOW7741QDFMRQ1 Quad-Channel Digital Isolator, 100 Mbps","metaDescription":"TI ISOW7741QDFMRQ1 quad-channel digital isolator with integrated isolated DC/DC, 100 Mbps data rate, 5000 Vrms isolation, AEC-Q100 automotive grade.","metaKeywords":null},"attributes":{"series":"ISOW774x-Q1","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Grade":"Automotive","Series":"ISOW774x-Q1","Package":"Tape & Reel (TR); Cut Tape (CT)","Data Rate":"100Mbps","Technology":"Capacitive Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Qualification":"AEC-Q100","Isolated Power":"Yes","Package / Case":"20-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.97V ~ 3.63V, 4.5V ~ 5.5V","Number of Channels":"4","Voltage - Isolation":"5000Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"3/1","Rise / Fall Time (Typ)":"2.5ns, 2.4ns","Supplier Device Package":"20-SOIC","Pulse Width Distortion (Max)":"5ns","Propagation Delay tpLH / tpHL (Max)":"15.7ns, 15.7ns","Common Mode Transient Immunity (Min)":"85kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.6","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$10.60000","currency":"USD"},{"qty":10,"price":"$9.74600","currency":"USD"},{"qty":25,"price":"$9.34240","currency":"USD"},{"qty":100,"price":"$8.23150","currency":"USD"},{"qty":250,"price":"$7.82752","currency":"USD"},{"qty":850,"price":"$7.32249","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/91cb7261c5dbd0cc15559a154f8267e8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I find the ISOW7741QDFMRQ1 datasheet?","answer":"The full datasheet is published by Texas Instruments under the ISOW774x-Q1 family.
