This means it generates its own isolated output power from the input supply, eliminating the need for a separate isolated power module on the BOM. It provides 2500Vrms isolation between input and output sides, with a unidirectional channel configuration — two channels on Side 2 receive data from Side 1. The data rate is rated at 1Mbps, with a maximum propagation delay of 70ns in both directions. The supply voltage range is split: 2.7V to 4.0V on one side, 4.5V to 5.5V on the other, reflecting the IsoPower converter's input and output rail requirements. The 2500Vrms isolation rating is a 1-minute withstand voltage per the standard. This is sufficient for basic isolation in industrial sensors, motor-drive interfaces, medical patient-monitoring equipment, and isolated power-supply feedback paths. It does not provide reinforced isolation for mains-connected medical devices — that typically requires 5000Vrms or higher. Because the IsoPower converter is integrated, the ADUM5242ARZ replaces a separate isolated DC/DC module plus a standard digital isolator, saving board area and reducing the component count on the isolated power rail. The trade-off is that the available isolated output power is limited — typically tens of milliwatts — so it is sized for powering a few low-power components on the isolated side, not an entire subsystem. ## 1Mbps data rate and 70ns propagation delay The 1Mbps data rate limits the digital channels to slow control signals, GPIO status, UART at moderate baud rates, or I2C-like signaling. It will not support high-speed SPI (typically 10-50Mbps) or full-speed CAN (1Mbps with tighter timing). The 70ns propagation delay is the maximum from input to output — budget this into any control-loop or timing-sensitive path. Rise and fall times are typically 2.5ns, which keeps edge-rate-induced emissions manageable. Common-mode transient immunity is rated at a minimum of 25kV/µs, meaning the output will not glitch when a fast high-voltage transient jumps across the isolation barrier — relevant for motor-drive and inverter applications. ## Lifecycle and compliance No special reflow profile beyond the standard JEDEC MSL rating applies — verify the specific MSL level from the latest datasheet if the part has been in storage.","metaTitle":"ADUM5242ARZ Digital Isolator, 2500Vrms, IsoPower, 1Mbps","metaDescription":"ADUM5242ARZ from Analog Devices: 2-channel general-purpose digital isolator with integrated isolated power.","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":"Tube","Data Rate":"1Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"Yes","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.7V ~ 4.0V, 4.5V ~ 5.5V","Number of Channels":"2","Voltage - Isolation":"2500Vrms","Operating Temperature":"-40°C ~ 105°C","Inputs - Side 1/Side 2":"0/2","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"8-SOIC","Pulse Width Distortion (Max)":"3ns","Propagation Delay tpLH / tpHL (Max)":"70ns, 70ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.18","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$9.18000","currency":"USD"},{"qty":10,"price":"$8.29500","currency":"USD"},{"qty":25,"price":"$7.90920","currency":"USD"},{"qty":100,"price":"$6.86760","currency":"USD"},{"qty":250,"price":"$6.55896","currency":"USD"},{"qty":500,"price":"$5.98020","currency":"USD"},{"qty":1000,"price":"$5.20857","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADUM5240_5241_5242.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does ADUM5242ARZ provide isolated power?","answer":"Yes, the ADUM5242ARZ integrates an IsoPower DC/DC converter that generates isolated output power from the input supply."},{"question":"What is the difference between ADUM5242ARZ and ADUM5241ARZ?","answer":"The ADUM5242ARZ has two unidirectional channels configured as 0 inputs on Side 1 and 2 inputs on Side 2, meaning both channels carry data from Side 1 to Side 2.
