It is rated for 5700 Vrms of isolation, making it suitable for safety-rated barriers in automotive traction inverters, battery management systems, on-board chargers, and industrial motor drives where reinforced isolation is required. The 5700 Vrms isolation voltage is the spec that determines whether this part can serve as a reinforced isolation barrier in a 400 V or 800 V traction system. It passes the 1-minute hipot test per IEC 60747-5-5, so you can use it in place of a discrete optocoupler + driver pair and save board area. The 85 kV/µs common-mode transient immunity (CMTI) is the number that matters when the isolator sits between a gate-driver PWM output and a controller on the low-voltage side: fast SiC or GaN switching edges can couple several kV/µs across the barrier, and if the isolator's CMTI is too low, the output glitches. At 85 kV/µs minimum, this part handles the transient environment of a modern traction inverter without extra filtering. ## Channel configuration and data rate The four channels are configured as three forward (side 1 to side 2) and one reverse (side 2 to side 1), which covers the typical SPI or UART interface: three lines for SPI (SCLK, MOSI, CS) and one for MISO return. The 100 Mbps data rate supports full-speed SPI clocking up to 100 MHz and CAN FD at 5 Mbps without adding latency. Propagation delay is 16 ns max, and pulse-width distortion is 4.9 ns max, so the timing budget for a daisy-chained ADC or isolated sensor link stays tight. ## Supply flexibility and package The supply range of 2.25 V to 5.5 V on each side means you can run the primary side at 3.3 V and the secondary at 5 V without a level shifter. No isolated power is integrated — you still need a separate DC-DC for the secondary-side rail. The 16-SOIC package (14.00 mm width) is a common footprint for high-isolation SOICs; it fits standard pick-and-place and reflow processes.","metaTitle":"TI ISO7741FQDWWQ1 digital isolator, 5700 Vrms, AEC-Q100","metaDescription":"TI ISO7741FQDWWQ1 general-purpose capacitive-coupling isolator, 4 channels, 100 Mbps, 5700 Vrms isolation, AEC-Q100 automotive qualified, -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","Grade":"Automotive","Series":"-","Package":"Tube","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":"$5.9000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c7679fc5c2d880a67021df2342c45ad1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is ISO7741FQDWWQ1 automotive qualified?","answer":"Yes, it is AEC-Q100 qualified, which is the standard stress-test qualification for automotive-grade ICs.
