What sets it apart from a plain isolator is the integrated isolated DC-DC converter — it generates a regulated output voltage on the isolated side from the input supply, so you don't need a separate isolated power module. That makes it a space-saving pick for designs where you need to pass a couple of digital signals across a safety barrier and also power a small circuit on the far side. The magnetic coupling technology handles 2500Vrms isolation, and the 1Mbps data rate covers most control and status-signal applications. The two channels are unidirectional, both oriented from Side 1 to Side 2 (0 inputs on Side 1, 2 outputs on Side 2). This matters if you need bidirectional communication — you'd need a second device for the return path. ## Isolation rating and what it buys you The 2500Vrms isolation voltage is a reinforced-grade rating for basic insulation in mains-connected industrial equipment, medical devices (non-patient-contact), and power supplies. The 25kV/µs common-mode transient immunity means the output won't glitch when a motor drive or inverter switches at high dv/dt — a common failure mode in cheaper optocoupler-based isolators. Not automotive-qualified (no AEC-Q100 in the record), but suitable for many factory-floor and instrumentation roles. ## Supply rails and the iso power output The part needs two supply domains. Side 1 (the logic input side) runs from 2.7V to 4.0V. Side 2 (the output side with the integrated iso power) needs 4.5V to 5.5V. The dual-range supply means you can interface a 3.3V microcontroller on Side 1 while Side 2 runs from a 5V rail and generates the isolated output. ## Timing specs for the bench Propagation delay is 70ns max in both directions, with a 3ns max pulse-width distortion. Rise and fall times are 2.5ns typical. That 70ns is fine for a 1Mbps data stream (1µs bit period gives plenty of margin), but if you're daisy-chaining several isolators in a signal path, the accumulated delay might matter for timing-critical loops. The 3ns PWD means the output pulse width stays close to the input — good for PWM signals where duty cycle accuracy matters. ## Package and board-level fit Housed in an 8-pin SOIC with 3.90mm body width (the narrow SOIC-8 footprint). Surface-mount only. No thermal pad on this package — dissipation is through the leads and board copper, so keep an eye on total power if you're pulling significant current from the iso power output at high ambient temperature. ## Sourcing and lifecycle posture For production BOMs, this is a low-risk line item with no imminent obsolescence concern.","metaTitle":"ADUM5242ARZ-RL7 Digital Isolator, 2500Vrms, IsoPower, 1Mbps","metaDescription":"ADUM5242ARZ-RL7 general-purpose digital isolator with integrated isolated DC-DC power. 2 channels, 2500Vrms isolation, 1Mbps data rate, -40 to 105°C, 8-SOIC.","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":"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 the ADUM5242ARZ-RL7 provide isolated power?","answer":"Yes.
