The channel configuration is three inputs on side 1 and one input on side 2, making it suitable for isolating SPI, UART, or general-purpose digital signals where the majority of traffic flows in one direction. ## 50 kV/µs CMTI — what it means for motor-drive and inverter designs The common-mode transient immunity of 50 kV/µs (minimum) is the key parameter for maintaining data integrity in environments with fast-switching power stages, such as traction inverters, DC-DC converters, and motor drives. A CMTI rating this high ensures that the output does not glitch when a high dv/dt transient couples across the isolation barrier — a common failure mode in SiC and GaN-based designs where switching edges exceed 50 V/ns. For a 3/1 channel part, the single reverse-direction channel is typically used for fault or status feedback, while the three forward channels carry PWM or data. ## Propagation delay and pulse-width distortion Maximum propagation delay of 165 ns (both directions) and pulse-width distortion of 10 ns define the timing budget for closed-loop control loops. At 4 Mbps, the bit period is 250 ns, so the 165 ns delay consumes about 66% of the period — adequate for most SPI and UART isolation applications, but the designer should verify setup/hold margins at the receiver. The 10 ns pulse-width distortion means the high and low pulses at the output differ by no more than 10 ns, which is tight enough for PWM duty-cycle accuracy in motor control. ## Active lifecycle and AEC-Q100 qualification It is fully ROHS3 compliant. The AEC-Q100 qualification (grade 1, implied by the 125°C operating temperature) covers the device for automotive under-hood and chassis-domain applications, as well as industrial environments requiring extended temperature range and reliability screening. ## Supply voltage and 5V system compatibility For a 5V system, the part operates at the upper end of the range, providing full 5V CMOS logic levels on both sides of the isolation barrier. The capacitive coupling technology does not require a separate isolated power supply for the data channels — the isolated power flag in the spec indicates the part includes an integrated DC-DC converter or supports an external isolated supply for the secondary side; in this device, the secondary-side logic power is derived from the primary-side supply through the isolation barrier, simplifying board layout.","metaTitle":"ISO7041QDBQRQ1 Automotive Quad-Channel Digital Isolator","metaDescription":"TI ISO7041QDBQRQ1 AEC-Q100 quad-channel digital isolator, 4 Mbps data rate, 3000Vrms isolation, 50 kV/µs CMTI, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100, ISO7041-Q1","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Series":"Automotive, AEC-Q100, ISO7041-Q1","Package":"Tape & Reel (TR); Cut Tape (CT)","Data Rate":"4Mbps","Technology":"Capacitive Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"Yes","Package / Case":"16-SSOP (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Number of Channels":"4","Voltage - Isolation":"3000Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"3/1","Rise / Fall Time (Typ)":"16ns, 16ns (Max)","Supplier Device Package":"16-SSOP","Pulse Width Distortion (Max)":"10ns","Propagation Delay tpLH / tpHL (Max)":"165ns, 165ns","Common Mode Transient Immunity (Min)":"50kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.79","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.79000","currency":"USD"},{"qty":10,"price":"$4.30600","currency":"USD"},{"qty":25,"price":"$4.07120","currency":"USD"},{"qty":100,"price":"$3.52840","currency":"USD"},{"qty":250,"price":"$3.34744","currency":"USD"},{"qty":500,"price":"$3.00364","currency":"USD"},{"qty":1000,"price":"$2.56050","currency":"USD"},{"qty":2500,"price":"$2.56050","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/eb6c340e3ff6de9ba7c60d2057e55f66.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is ISO7041QDBQRQ1 AEC-Q100 qualified?","answer":"Yes, the ISO7041QDBQRQ1 is part of the Automotive, AEC-Q100 series (ISO7041-Q1), qualified for automotive applications."},{"question":"Can ISO7041QDBQRQ1 be used in 5V systems?","answer":"Yes, the supply voltage range of 3V to 5.5V covers 5V operation directly.
