It is a general-purpose part meant for applications where galvanic isolation is mandatory: industrial fieldbus interfaces, motor-drive feedback paths, medical patient-contact circuits, and isolated SPI or UART links. The unidirectional channel configuration — one input on side 1, one on side 2 — suits simple data-flow separation, not bidirectional buses. ## 150 Mbps and 75 kV/µs CMTI — the margin numbers Rated at 150 Mbps, this part handles fast serial links like SPI at 50 MHz clock rates or UART at several Mbps without timing pressure. Propagation delay is 13 ns max in both directions, and pulse-width distortion stays under 3 ns — tight enough for most isolated data paths. The 75 kV/µs common-mode transient immunity is the spec that matters in noisy environments: motor drives, inverters, and switch-mode power supplies generate fast voltage transients across the barrier. A part with lower CMTI will glitch or latch in those conditions; this one holds the data line clean. ## Lifecycle and supply position ADI lists the ADUM221N1BRWZ as an active product with ROHS3 compliance.","metaTitle":"ADUM221N1BRWZ Digital Isolator, 5000Vrms, 150Mbps, 2-Channel","metaDescription":"ADI ADUM221N1BRWZ iCoupler 2-channel digital isolator: 5000Vrms isolation, 150Mbps data rate, 75kV/µs CMTI, -40°C to 125°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":"Tube","Data Rate":"150Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"1.7V ~ 5.5V","Number of Channels":"2","Voltage - Isolation":"5000Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"1/1","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"16-SOIC","Pulse Width Distortion (Max)":"3ns","Propagation Delay tpLH / tpHL (Max)":"13ns, 13ns","Common Mode Transient Immunity (Min)":"75kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.51","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.51000","currency":"USD"},{"qty":10,"price":"$3.14900","currency":"USD"},{"qty":25,"price":"$2.97680","currency":"USD"},{"qty":100,"price":"$2.58000","currency":"USD"},{"qty":250,"price":"$2.44772","currency":"USD"},{"qty":500,"price":"$2.19634","currency":"USD"},{"qty":1000,"price":"$1.85234","currency":"USD"},{"qty":2500,"price":"$1.75972","currency":"USD"},{"qty":5000,"price":"$1.69357","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADuM220N-221N-225N-226N.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the data rate of the ADUM221N1BRWZ?","answer":"The ADUM221N1BRWZ supports a data rate of 150 Mbps, suitable for isolating high-speed serial interfaces like SPI."},{"question":"Is the ADUM221N1BRWZ a 2-channel isolator?","answer":"Yes, it has two unidirectional channels with one input on side 1 and one input on side 2."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADUM221N1BRWZ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADUM221N1BRWZ when reusing this data.
