The 3/1 input-side/side-2 split (three channels forward, one reverse) suits half-duplex interfaces like RS-485 or SPI with a single feedback line. ## 25 kV/µs CMTI — why it matters for motor drives and inverters Common-mode transient immunity of 25 kV/µs (minimum) means this isolator keeps data intact when fast voltage spikes slam across the barrier — exactly what happens in motor-drive phases, solar inverters, and industrial power stages. Pulse-width distortion is held to 3 ns max, so the pulse shape stays clean enough for PWM or timing-sensitive links. It comes in a 16-SOIC wide-body (7.50 mm width) package — surface-mount only, no isolated power output on this variant. The Tube shipping medium is fine for prototype or low-volume builds; for reels check the alternate order code. ## Lifecycle and compliance No official second-source cross-reference exists in the iCoupler family, but the ADUM2401BRIZ shares the same 3/1 channel direction, 10 Mbps data rate, and 5000 Vrms isolation in a similar 16-SOIC package, making it a functional alternative for dual-sourcing evaluation.","metaTitle":"ADUM4401BRWZ iCoupler Digital Isolator, 5000Vrms, 10Mbps","metaDescription":"ADUM4401BRWZ general-purpose 4-channel digital isolator. 5000Vrms isolation, 10Mbps data rate, 25kV/µs CMTI.
