It packs four inputs on side 1 and two on side 2, which maps directly to the typical SPI bus: SCK, MOSI, MISO, and chip-select on the controller side, with two interrupt or handshake lines returning. The 40Mbps data rate keeps up with SPI clock rates up to 40 MHz without adding a cycle of latency — propagation delay is 24ns max each way, and pulse-width distortion stays under 2ns. That timing budget matters when the bus is running near its limit through a long cable or backplane. Supply range of 3V to 5.5V on both sides means this part works with 3.3V and 5V SPI domains without a level shifter. The 5000Vrms isolation rating is reinforced-grade — suitable for medical equipment (2 MOPP with proper creepage), motor-drive interfaces, and industrial fieldbus isolation where the environment demands a hard galvanic barrier. Common-mode transient immunity of 25kV/µs minimum keeps the data path clean in noisy inverter or relay-switching environments. The 20-SOIC wide-body package (7.50mm width) provides the creepage distance needed to sustain the 5000Vrms rating across the isolation barrier. ## Channel count and directionality — the fit check Six unidirectional channels with a 4/2 split (four from side 1 to side 2, two from side 2 to side 1) are purpose-configured for SPI isolation. The four forward channels carry SCK, MOSI, and two chip-select or data lines; the two reverse channels handle MISO and an interrupt or busy signal. If your SPI peripheral needs more than two reverse-direction signals — say, a second MISO or a fault output — you will need a second isolator or a part with a different channel configuration.","metaTitle":"ADUM4150ARIZ-RL SPI Digital Isolator, 5000Vrms, 40Mbps","metaDescription":"ADUM4150ARIZ-RL 6-channel SPI digital isolator from ADI. 5000Vrms isolation, 40Mbps data rate, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":"iCoupler®, SPIsolator™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"SPI","Series":"iCoupler®, SPIsolator™","Package":"Tape & Reel (TR); Cut Tape (CT)","Data Rate":"40Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"20-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Number of Channels":"6","Voltage - Isolation":"5000Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"4/2","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"20-SOIC-IC","Pulse Width Distortion (Max)":"2ns","Propagation Delay tpLH / tpHL (Max)":"24ns, 24ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.21","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$13.21000","currency":"USD"},{"qty":10,"price":"$12.14400","currency":"USD"},{"qty":25,"price":"$11.64080","currency":"USD"},{"qty":100,"price":"$10.25640","currency":"USD"},{"qty":250,"price":"$9.75308","currency":"USD"},{"qty":500,"price":"$9.12384","currency":"USD"},{"qty":1000,"price":"$8.36876","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADuM4150.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does ADUM4150ARIZ-RL work with 5V SPI?","answer":"Yes.
