It provides 1000Vrms of galvanic isolation across two input channels on side 1 and two on side 2, all running unidirectional at up to 25Mbps. The 2ns typical rise/fall time keeps signal integrity clean for SPI, UART, or general-purpose GPIO isolation at that speed. ## 15kV/µs CMTI — keeps data through motor-drive noise Common-mode transient immunity is rated at a minimum of 15kV/µs. That matters when the isolator sits between a noisy motor-drive inverter and a sensitive controller — fast voltage spikes on the isolated side won't glitch the output logic. The 50ns max propagation delay (same in both directions) gives predictable timing for synchronous interfaces. ## Supply flexibility: 3V to 5.5V on both sides The supply range spans 3V to 5.5V, so the same part can bridge a 3.3V MCU to a 5V sensor or actuator without external level shifters. ## Active lifecycle — no end-of-life pressure ROHS3 compliant, so it passes current environmental regulations without exemption paperwork.","metaTitle":"ADUM7442CRQZ-RL7 iCoupler Digital Isolator, 25Mbps, 1000Vrms","metaDescription":"ADUM7442CRQZ-RL7 is a 4-channel unidirectional digital isolator from the iCoupler series. 25Mbps data rate, 1000Vrms isolation, 15kV/µs CMTI.","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":"25Mbps","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":"2/2","Rise / Fall Time (Typ)":"2ns, 2ns","Supplier Device Package":"16-QSOP","Pulse Width Distortion (Max)":"5ns","Propagation Delay tpLH / tpHL (Max)":"50ns, 50ns","Common Mode Transient Immunity (Min)":"15kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.28","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$7.28000","currency":"USD"},{"qty":10,"price":"$6.58000","currency":"USD"},{"qty":25,"price":"$6.27360","currency":"USD"},{"qty":100,"price":"$5.44730","currency":"USD"},{"qty":250,"price":"$5.20252","currency":"USD"},{"qty":500,"price":"$4.74346","currency":"USD"},{"qty":1000,"price":"$4.13140","currency":"USD"},{"qty":2000,"price":"$3.97839","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADuM7440_7441_7442.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between ADUM7442CRQZ-RL7 and ADUM7441CRQZ-RL7?","answer":"Both are 4-channel unidirectional isolators at 25Mbps with the same package and isolation rating.
