It supports a data rate of 150 Mbps with propagation delays of 7.5 ns (tpLH) and 7.4 ns (tpHL) and pulse-width distortion under 1 ns. The supply range spans 1.71 V to 5.5 V. The 150 Mbps data rate covers most high-speed serial protocols. The 2750 Vrms isolation rating is a basic insulation level for mains-referenced circuits. The 25 kV/µs typical common-mode transient immunity ensures the output doesn't glitch when fast voltage transients appear across the isolation barrier. ## Channel configuration and supply flexibility Three channels on side 1, one on side 2 — a 3/1 split that suits a typical SPI isolation pattern (SCLK, MOSI, CS on one side, MISO on the other) or a three-signal control bus with one feedback line. All channels are unidirectional, so the direction is fixed at design time. No isolated power is generated internally — you must provide separate supply rails on each side. The 125°C upper limit covers most sealed enclosures and engine-bay-adjacent locations. ## Package and rework considerations The lead pitch is wide enough that bridging is unlikely with a fine-tip iron. No exposed thermal pad, so the part dissipates through the leads and the board copper. The part ships in Tube. ## Lifecycle and sourcing posture It is ROHS3 compliant.","metaTitle":"MAX14931FAWE+ Digital Isolator, 150Mbps, 2750Vrms, 16-SOIC","metaDescription":"Maxim MAX14931FAWE+ general-purpose digital isolator with 150Mbps data rate, 2750Vrms isolation, capacitive coupling, 4 unidirectional channels, -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":"Capacitive 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":"1.71V ~ 5.5V","Number of Channels":"4","Voltage - Isolation":"2750Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"3/1","Rise / Fall Time (Typ)":"2ns, 2ns","Supplier Device Package":"16-SOIC","Pulse Width Distortion (Max)":"1ns","Propagation Delay tpLH / tpHL (Max)":"7.5ns, 7.4ns","Common Mode Transient Immunity (Min)":"25kV/µs (Typ)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.71","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$7.71000","currency":"USD"},{"qty":10,"price":"$6.96400","currency":"USD"},{"qty":25,"price":"$6.64000","currency":"USD"},{"qty":100,"price":"$5.76550","currency":"USD"},{"qty":250,"price":"$5.50640","currency":"USD"},{"qty":500,"price":"$5.02054","currency":"USD"},{"qty":1000,"price":"$4.85859","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/max14130-max14932.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MAX14931FAWE+ support 150Mbps data rate?","answer":"Yes, the MAX14931FAWE+ is specified for a data rate of 150 Mbps.
