It delivers 1000Vrms isolation across a 3V to 5.5V supply range, making it a straight drop-in for splitting ground domains on mixed-voltage boards — think 3.3V MCU talking to a 5V sensor or actuator on the other side. The 1Mbps data rate handles SPI clock lines, UART TX/RX pairs, and general-purpose GPIO isolation without timing pressure; propagation delay is 75ns max each way with 25ns pulse-width distortion. Three channels run from Side 1 to Side 2, one channel runs the opposite direction, which maps cleanly to a typical SPI bus (SCLK, MOSI, CS out, MISO back) or a UART with flow control. ## 15kV/µs CMTI — the motor-drive spec That is the number that matters when this isolator sits between a controller and a gate-driver or inverter phase leg — fast voltage swings on the high-side ground will couple through parasitic capacitance, and if the CMTI is too low the output glitches. 15kV/µs is sufficient for most industrial drives and power supplies up to several hundred volts of bus voltage. The 2ns typical rise/fall time keeps edge rates clean enough that signal integrity on the isolated side stays within budget without external schmitt triggers. ## Supply flexibility: 3V to 5.5V on both sides Both isolation sides share the same 3V to 5.5V supply range, so you can run the primary at 3.3V and the secondary at 5V — or match them — without a separate level translator. The 16-QSOP footprint (3.90mm body width) is a space-saver compared to SOIC-16 wide-body isolators, useful when board area is tight.","metaTitle":"ADUM7441ARQZ-RL7 Digital Isolator, 1Mbps, 1000Vrms, 16-QSOP","metaDescription":"ADI ADUM7441ARQZ-RL7 iCoupler 4-channel digital isolator, 1Mbps data rate, 1000Vrms isolation, 3V-5.5V supply, -40°C to 105°C.","metaKeywords":null},"attributes":{"series":"iCoupler®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Series":"iCoupler®","Package":"Tape & Reel (TR); Cut Tape (CT)","Data Rate":"1Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"16-SSOP (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Number of Channels":"4","Voltage - Isolation":"1000Vrms","Operating Temperature":"-40°C ~ 105°C","Inputs - Side 1/Side 2":"3/1","Rise / Fall Time (Typ)":"2ns, 2ns","Supplier Device Package":"16-QSOP","Pulse Width Distortion (Max)":"25ns","Propagation Delay tpLH / tpHL (Max)":"75ns, 75ns","Common Mode Transient Immunity (Min)":"15kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.35","priceTiers":[{"qty":1,"price":"$5.35000","currency":"USD"},{"qty":10,"price":"$4.80800","currency":"USD"},{"qty":25,"price":"$4.54480","currency":"USD"},{"qty":100,"price":"$3.93900","currency":"USD"},{"qty":250,"price":"$3.73700","currency":"USD"},{"qty":500,"price":"$3.35320","currency":"USD"},{"qty":1000,"price":"$2.82800","currency":"USD"},{"qty":2000,"price":"$2.68660","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ADUM7441ARQZ-RL7/alternatives.json"},"ai":{"faq":[{"question":"What are the alternatives to ADUM7441ARQZ-RL7?","answer":"The ADUM7442ARQZ-RL7 is the same 4-channel unidirectional isolator but with a 2/2 input split (two channels each direction) instead of the 3/1 split on the ADUM7441.
