It pushes 100Mbps per channel with 2.5ns typical rise/fall times and 24ns max propagation delay, making it a fit for isolating SPI buses, CAN FD, or high-speed UART links where you need to keep the data rate up. The 3000Vrms isolation rating and 25kV/µs common-mode transient immunity handle the noisy environments found in motor drives, inverters, and industrial fieldbus interfaces. ## Channel direction and supply flexibility Both channels run from Side 1 to Side 2 (2/0 input/output split), so this part handles downstream isolation — controller to peripheral — in a single package. The 3V to 5.5V supply range on each side lets you level-shift between a 3.3V MCU domain and a 5V sensor or actuator interface without extra translation logic. Pulse width distortion stays under 2ns max, which keeps the duty cycle intact for PWM or encoder signals crossing the barrier. ## Package and temperature fit Housed in the 8-SOIC narrow-body footprint (3.90mm width), surface-mount only. No isolated DC-DC converter on-chip — you supply the isolated power rail separately, which is typical for this channel count and data rate tier.","metaTitle":"ADUM1285CRZ Digital Isolator, 100Mbps, 3000Vrms, 8-SOIC","metaDescription":"ADUM1285CRZ iCoupler 2-channel unidirectional digital isolator. 100Mbps data rate, 3000Vrms isolation, 25kV/µs CMTI, -40°C to 125°C.
