Propagation delay is 16ns max (tpLH / tpHL), with pulse-width distortion held to 4.9ns max — tight enough for timing-sensitive links like isolated SPI clock and data. ## Channel configuration and package The device provides 3 channels on side 1 and 1 channel on side 2, all unidirectional. This 3/1 split suits applications like isolated SPI (SCLK, MOSI, CS from the controller side, MISO returning) or isolated UART (TX, RX plus a control signal). The 16-SOIC wide-body package (0.551\" body width, 14.00mm) provides the creepage distance needed for 5700Vrms reinforced isolation in a surface-mount footprint. Rise and fall times are 2.4ns typical, keeping signal edges clean at 100Mbps.","metaTitle":"ISO7741FQDWWRQ1 Automotive Digital Isolator, 100Mbps","metaDescription":"TI ISO7741FQDWWRQ1 automotive-grade capacitive coupling digital isolator. 4 channels, 100Mbps data rate, 5700Vrms isolation, AEC-Q100 qualified.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Mfr":"Texas Instruments","Type":"General Purpose","Grade":"Automotive","Series":"-","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":"No","Package / Case":"16-SOIC (0.551\\\", 14.00mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"2.25V ~ 5.5V","Number of Channels":"4","Base Product Number":"ISO7741","Voltage - Isolation":"5700Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"3/1","Rise / Fall Time (Typ)":"2.4ns, 2.4ns","Supplier Device Package":"16-SOIC","Pulse Width Distortion (Max)":"4.9ns","Propagation Delay tpLH / tpHL (Max)":"16ns, 16ns","Common Mode Transient Immunity (Min)":"85kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.2700","priceTiers":[{"qty":1,"price":"$5.27000","currency":"USD"},{"qty":10,"price":"$4.73100","currency":"USD"},{"qty":25,"price":"$4.47240","currency":"USD"},{"qty":100,"price":"$3.87600","currency":"USD"},{"qty":250,"price":"$3.67720","currency":"USD"},{"qty":500,"price":"$3.29954","currency":"USD"},{"qty":1000,"price":"$2.78275","currency":"USD"},{"qty":2000,"price":"$2.64362","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c7679fc5c2d880a67021df2342c45ad1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ISO7741FQDWWRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is ISO7741FQDWWRQ1 AEC-Q100 qualified?","answer":"Yes, the part is AEC-Q100 qualified, confirming its suitability for automotive-grade designs including under-hood and cabin environments."},{"question":"Can ISO7741FQDWWRQ1 be used in 5V systems?","answer":"Yes.
