It integrates isolated power transfer into the same package as the signal isolation, meaning you get a 5000 Vrms reinforced isolation barrier and a 100 Mbps data path without needing a separate isolated DC-DC converter module on the secondary side. The magnetic coupling technology handles the isolation, and the IsoPower block generates the isolated-side supply rail internally. For a field swap or a BOM line that needs to shrink board area, this part collapses what used to be two or three components into one 28-SOIC-W-FP package. ## 5000 Vrms — what that buys you in the real world A 5000 Vrms isolation rating is reinforced-grade for IEC 60747-17 and UL 1577. That covers motor-drive phase-to-ground isolation, medical patient-contact barrier (2 MOPP with creepage), and industrial fieldbus isolation where transient overvoltages hit several kilovolts. The 75 kV/µs common-mode transient immunity means this isolator won't glitch when a nearby IGBT switches 600 V in a few nanoseconds — a common failure mode with optocoupler-based designs. The 17 ns max propagation delay in each direction keeps timing closure tight for a 100 Mbps SPI clock or a CAN bus bit sample point. ## Supply range and temperature — where it lives on the board The 28-SOIC-W-FP package has a 7.50 mm body width and 0.295 inch pitch — a standard SOIC footprint that rework techs can hand-solder with a fine tip if the board layout gives access. ## Unidirectional channels — what the 4/0 input-side count means All four channels are unidirectional with all inputs on side 1 and all outputs on side 2. That is a deliberate topology for isolating a 4-bit parallel bus, a SPI bus (SCLK, MOSI, CS, and one extra), or four discrete control signals from a controller to a remote transceiver. If you need bidirectional isolation (e.g., for a half-duplex RS-485), you would need a different channel configuration or two devices. The 2.5 ns typical rise/fall time keeps signal integrity clean at 100 Mbps without excessive edge-rate ringing.","metaTitle":"ADUM6420ABRNZ5-RL Digital Isolator, 5000Vrms, 100Mbps","metaDescription":"ADUM6420ABRNZ5-RL from Analog Devices: 4-channel digital isolator with 5000Vrms isolation, 100Mbps data rate, integrated IsoPower. -40°C to 125°C.","metaKeywords":null},"attributes":{"series":"IsoPower®, iCoupler®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Series":"IsoPower®, iCoupler®","Package":"Tape & Reel (TR); Cut Tape (CT)","Data Rate":"100Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"Yes","Package / Case":"28-BSSOP (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"1.7V ~ 5.5V","Number of Channels":"4","Voltage - Isolation":"5000Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"4/0","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"28-SOIC-W-FP","Pulse Width Distortion (Max)":"5ns","Propagation Delay tpLH / tpHL (Max)":"17ns, 17ns","Common Mode Transient Immunity (Min)":"75kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$15.21","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$15.21000","currency":"USD"},{"qty":10,"price":"$13.97600","currency":"USD"},{"qty":25,"price":"$13.39720","currency":"USD"},{"qty":100,"price":"$11.80400","currency":"USD"},{"qty":250,"price":"$11.22464","currency":"USD"},{"qty":500,"price":"$10.50046","currency":"USD"},{"qty":1000,"price":"$9.63146","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/adum6420a-6421a-6422a_6423a_6424a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between ADUM6420 and ADUM6421?","answer":"The ADUM6421 typically offers a different channel direction configuration (e.g., some channels reversed).
