It supports data rates up to 100Mbps with a maximum propagation delay of 24ns and typical rise/fall times of 2.5ns, making it suitable for isolating high-speed digital interfaces like SPI, UART, or general-purpose GPIO lines where galvanic isolation is required for safety or noise immunity. The 5000Vrms isolation rating is the key spec for designs requiring reinforced insulation per IEC 60747-5-5 or VDE 0884-10. This part provides a single-channel isolation barrier for two unidirectional signals (both inputs on Side 1, no outputs on Side 2), which means it handles two downstream signals from one isolated domain. The 16-SOIC wide-body package provides the physical creepage (≥8mm typical for this footprint) to support the voltage rating in PCB layouts where clearance is tight. Common-mode transient immunity of 25kV/µs minimum ensures the output doesn't glitch when fast high-voltage transients couple across the barrier — critical in motor-drive inverters, industrial power supplies, or any environment with SiC/GaN switching edges. If your system sees faster transients, you'll need a part with higher CMTI, but 25kV/µs covers most IGBT-based drives and 400V AC line applications. ## Speed and timing budget for the bus At 100Mbps, the ADUM2285CRIZ handles SPI clock rates up to 50MHz (NRZ) with margin. The 24ns max propagation delay (tpLH/tpHL) and 2ns max pulse-width distortion mean the isolated data stream preserves pulse symmetry well enough for most synchronous interfaces. The 2.5ns typical rise/fall times keep signal edges clean without excessive EMI, but you'll still want a series termination resistor close to the output pin if driving a long trace.","metaTitle":"ADUM2285CRIZ Digital Isolator, 100Mbps, 5000Vrms, 16-SOIC","metaDescription":"ADUM2285CRIZ iCoupler 2-channel unidirectional digital isolator. 100Mbps data rate, 5000Vrms isolation, -40°C to 125°C.
