It provides galvanic isolation up to 1000Vrms between input and output sides, with a data rate of 1Mbps — fast enough for most industrial UART, SPI, and general-purpose logic-level isolation needs. The 1000Vrms isolation rating defines the basic insulation level for this device — suitable for applications where the working voltage stays well below that threshold, such as industrial sensor interfaces, PLC I/O modules, and isolated data acquisition. The 15kV/µs common-mode transient immunity (CMTI) is the spec that matters when the isolator sits near a switching power stage or motor drive: fast voltage transients across the isolation barrier can corrupt data if the CMTI isn't high enough. At 15kV/µs minimum, this part handles the edge rates from a typical IGBT or SiC MOSFET gate driver without bit errors. ## Propagation delay and pulse-width distortion — timing budget factors Maximum propagation delay is 75ns in either direction, with a pulse-width distortion limit of 25ns. For a 1Mbps signal (1µs period), that 75ns adds about 7.5% to the total path delay — acceptable for most asynchronous interfaces but worth budgeting if the isolator sits in a closed-loop control path or a timing-critical SPI bus. The 2ns typical rise/fall time keeps signal edges clean at 1Mbps without excessive ringing. ## Package and supply — footprint and rail planning Housed in an 8-pin SOIC (3.90mm body width), surface-mount only. The supply range of 3V to 5.5V on each side means a single 3.3V rail powers both sides for a 3.3V-only system, or you run Vdd1 at 3.3V and Vdd2 at 5V for mixed-voltage isolation. No isolated power is generated internally — each side needs its own supply rail and decoupling. ## Lifecycle and compliance — no end-of-life risk For dual-source planning, the closest functional peer in the same iCoupler family is the ADUM7442ARQZ-RL7 — a 4-channel unidirectional isolator with otherwise identical ratings (1Mbps, 1000Vrms, 75ns propagation delay, 15kV/µs CMTI). If your BOM needs more channels in the same footprint, that part is a drop-in consideration; for a 2-channel requirement, this is the direct fit.","metaTitle":"ADUM7241ARZ-RL7 iCoupler Digital Isolator, 1000Vrms, 1Mbps","metaDescription":"ADUM7241ARZ-RL7 iCoupler digital isolator from Analog Devices. 2 channels, 1000Vrms isolation, 1Mbps data rate, 15kV/µs CMTI.
