The 2/2 input-to-output channel split (two channels on side 1, two on side 2) matches the common pattern of two control outputs and two feedback inputs in a motor-drive or PLC I/O module. ## 1 Mbps with 90 ns propagation delay — timing budget for isolated links At 1 Mbps, the 90 ns max propagation delay (tpLH / tpHL) and 6 ns max pulse-width distortion keep the timing margin tight but workable for most 1 MHz SPI clocks and UART bit rates up to 115.2 kbaud. The 2.5 ns typical rise/fall time limits edge-rate ringing on short PCB traces. If your design needs 10 Mbps or higher, step to the ADUM3482BRSZ variant (25 Mbps) — same pinout, same package, same 3750 Vrms isolation. ## 3750 Vrms isolation and 25 kV/µs CMTI — noise immunity in motor drives and inverters The 3750 Vrms isolation rating satisfies basic reinforced insulation for 300 Vrms working voltage per IEC 60747-5-5, suitable for medical equipment (BF-rated patient connections) and industrial drives. The 25 kV/µs minimum common-mode transient immunity ensures data doesn't glitch when a motor drive switches a 600 V DC bus at 20 kHz — a common failure point in optocoupler-based designs. Each side of the isolator has its own supply pin, allowing a 3.3 V controller side and a 5 V sensor side (or 1.8 V low-power side). This split-rail capability eliminates level-shifter ICs when bridging a 1.8 V MCU to a 5 V peripheral.","metaTitle":"ADUM3482ARSZ iCoupler Digital Isolator, 1Mbps, 3750Vrms","metaDescription":"ADUM3482ARSZ 4-channel unidirectional digital isolator, 1 Mbps data rate, 3750 Vrms isolation, 25 kV/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":"1Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"20-SSOP (0.209\\\", 5.30mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"1.8V ~ 5.5V, 3V ~ 5.5V","Number of Channels":"4","Voltage - Isolation":"3750Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"2/2","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"20-SSOP","Pulse Width Distortion (Max)":"6ns","Propagation Delay tpLH / tpHL (Max)":"90ns, 90ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.49","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.49000","currency":"USD"},{"qty":10,"price":"$4.92800","currency":"USD"},{"qty":25,"price":"$4.65880","currency":"USD"},{"qty":100,"price":"$4.03750","currency":"USD"},{"qty":250,"price":"$3.83044","currency":"USD"},{"qty":500,"price":"$3.43704","currency":"USD"},{"qty":1000,"price":"$2.89870","currency":"USD"},{"qty":2500,"price":"$2.75376","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADuM3480_3481_3482.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the data rate of ADUM3482ARSZ?","answer":"The ADUM3482ARSZ is rated for 1 Mbps data rate.
