Its channel configuration is five inputs on side 1 and one input on side 2 — an asymmetric split that suits applications like isolated SPI (SCLK, MOSI, MISO, CS plus a control signal out, with one feedback line back) or multi-sensor data acquisition where the bulk of signals flow one direction. The 150 Mbps data rate handles most industrial serial links comfortably, and the 75 kV/µs common-mode transient immunity keeps data intact across the barrier when motor drives or inverters slam the ground reference around. ## What the 3000 Vrms and 75 kV/µs ratings mean on the board The 3000 Vrms isolation rating qualifies this part for basic insulation in mains-connected industrial equipment per IEC 60747-17. The 75 kV/µs common-mode transient immunity (CMTI) is the spec that matters when you place this isolator between a noisy power stage and a sensitive controller — fast SiC or GaN switching edges can couple tens of kV/µs across the barrier, and if the isolator's CMTI is too low, data corrupts or the output latches. At 75 kV/µs minimum, this part handles the switching speeds of modern wide-bandgap power stages without extra filtering. ## Supply flexibility and timing margins Propagation delay is 13 ns max in either direction, with 4.5 ns max pulse-width distortion — tight enough for 150 Mbps NRZ data with enough margin for a clean eye at the receiver. Rise and fall times are 2.5 ns typical, which keeps edge-rate-induced ringing manageable on short SOIC traces. ## Lifecycle and sourcing posture No official replacement or second-source alternate is recorded, but the iCoupler family has broad pin-compatible density options if a design needs fewer channels or a different direction split.","metaTitle":"ADUM161N1BRZ Digital Isolator, 6-Ch, 150Mbps, 3000Vrms","metaDescription":"ADUM161N1BRZ 6-channel digital isolator with magnetic coupling, 150Mbps data rate, 3000Vrms isolation, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Package":"Tube","Data Rate":"150Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"1.7V ~ 5.5V","Number of Channels":"6","Voltage - Isolation":"3000Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"5/1","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"16-SOIC","Pulse Width Distortion (Max)":"4.5ns","Propagation Delay tpLH / tpHL (Max)":"13ns, 13ns","Common Mode Transient Immunity (Min)":"75kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.35","stockQuantity":0,"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":2500,"price":"$2.68660","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADuM160N-161N-162N-163N.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How many channels does ADUM161N1BRZ have and what is the direction configuration?","answer":"Six channels total, with five inputs on side 1 and one input on side 2 — an asymmetric 5/1 split."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADUM161N1BRZ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADUM161N1BRZ when reusing this data.
