A CMTI below 50 kV/µs risks bit errors at switching edges. The 85 kV/µs rating provides margin for 100 V/ns slew rates typical of 650 V GaN devices. This part is qualified for new design-ins and volume production without supply discontinuity risk. ## 3/1 channel direction — three forward, one reverse The channel configuration is 3 inputs on side 1, 1 input on side 2. This suits a typical SPI isolation interface: three forward channels (SCLK, MOSI, CS) and one reverse channel (MISO). The unidirectional architecture avoids the dead-time and direction-control overhead of bidirectional isolators.","metaTitle":"ISO7741QDWWRQ1 Automotive Digital Isolator, 5700 Vrms","metaDescription":"TI ISO7741QDWWRQ1 4-channel capacitive isolator, AEC-Q100, 5700 Vrms, 100 Mbps, 85 kV/µs CMTI, -40°C to 125°C, 16-SOIC.","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":"$5.2900","priceTiers":[{"qty":1,"price":"$5.29000","currency":"USD"},{"qty":10,"price":"$4.75500","currency":"USD"},{"qty":25,"price":"$4.49520","currency":"USD"},{"qty":100,"price":"$3.89570","currency":"USD"},{"qty":250,"price":"$3.69588","currency":"USD"},{"qty":500,"price":"$3.31632","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/ISO7741QDWWRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is ISO7741QDWWRQ1 AEC-Q100 qualified for automotive?","answer":"Yes, the ISO7741QDWWRQ1 is AEC-Q100 qualified, making it suitable for automotive applications including under-hood and chassis-domain isolation."},{"question":"What is the difference between ISO7741 and ISO7740?","answer":"The ISO7741 provides 4 channels with a 3/1 direction split (three forward, one reverse), while the ISO7740 offers 4 channels with a 4/0 split (all forward).
