It delivers 3750 Vrms of galvanic isolation across the barrier while maintaining a 1 Mbps data rate on each channel. The 2/2 input/output split (Side 1/Side 2) suits it for splitting a bus or isolating two signals on each side. Propagation delay is 90 ns max in either direction, with pulse width distortion held to 6 ns max — tight enough for SPI and UART links where edge symmetry matters. ## Supply flexibility and temperature range That means it can bridge a 1.8 V MCU domain to a 5 V peripheral bus without a separate level shifter. Rise and fall times are 2.5 ns typical, keeping the edges clean at 1 Mbps without excessive EMI. ## Common-mode transient immunity — 25 kV/µs With a minimum common-mode transient immunity (CMTI) of 25 kV/µs, this isolator handles fast voltage transients across the barrier — the kind you see in motor drives, inverter stages, and switched-mode power supplies where high dV/dt couples across the isolation gap. That rating is the practical limit for reliable data transmission in those environments. ## Package and mounting Supplied in a 20-lead SSOP package (0.209\" body width, 5.30 mm) for surface-mount assembly. The 20-SSOP footprint is shared with other ADI isolators in the same channel count, so a board layout can often accommodate alternate density options. ## Lifecycle and sourcing It is ROHS3 compliant.","metaTitle":"ADUM3482ARSZ-RL7 Digital Isolator, 3750Vrms, 1Mbps, 20-SSOP","metaDescription":"ADUM3482ARSZ-RL7 iCoupler digital isolator, 4-ch unidirectional, 3750Vrms isolation, 1Mbps data rate, -40°C to 125°C, 20-SSOP.","metaKeywords":null},"attributes":{"series":"iCoupler®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Series":"iCoupler®","Package":"Tape & Reel (TR); Cut Tape (CT)","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":"$5.76","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.76000","currency":"USD"},{"qty":10,"price":"$5.17200","currency":"USD"},{"qty":25,"price":"$4.88920","currency":"USD"},{"qty":100,"price":"$4.23740","currency":"USD"},{"qty":250,"price":"$4.02004","currency":"USD"},{"qty":500,"price":"$3.60718","currency":"USD"},{"qty":1000,"price":"$3.07500","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADuM3480_3481_3482.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can ADUM3482ARSZ-RL7 be used in 5V systems?","answer":"Yes.

The ADUM3482ARSZ (without the -RL7 suffix) is typically supplied in tube or tray. The die, performance, and package are identical."},{"question":"Is ADUM3482ARSZ-RL7 compatible with ADUM3482ARSZ?","answer":"Yes, they are the same device. The -RL7 suffix only denotes the Tape & Reel packaging format. They are pin-compatible and functionally identical."},{"question":"What is an equivalent for ADUM3482ARSZ-RL7?","answer":"Within the same iCoupler family, the ADUM3480 series offers similar channel counts and isolation ratings. For a pin-compatible alternate, check the ADUM3481 (3/1 channel split) or ADUM3480 (1/3 split) in the same 20-SSOP package.
