The 1Mbps data rate and 100ns propagation delay suit status feedback, slow SPI (sub-1MHz), and GPIO isolation; it is not a candidate for high-speed fieldbuses or isolated serial links above 1Mbps. ## Channel direction — the 2/2 split that sets it apart The ADUM4402ARWZ allocates its four channels as two inputs on Side 1 and two inputs on Side 2 — a symmetric 2/2 split. This is the key difference from the ADUM4401 (3/1 split) and ADUM4403 (1/3 split) in the same family. For a half-duplex UART isolation or a bidirectional control interface where you need equal channel count each way, the 2/2 split avoids wasting a channel. The unidirectional channel type means each channel's direction is fixed at the silicon level; the split is not configurable, so verify your signal direction map against the 2/2 assignment before layout. ## Common-mode transient immunity — the 25kV/µs floor The minimum common-mode transient immunity of 25kV/µs is the spec that determines whether the isolator holds data integrity when a high-voltage switching node (IGBT gate driver, MOSFET half-bridge) slams the barrier with a fast voltage step. In a motor-drive or inverter application, a CMTI below the system's dV/dt can corrupt the output for tens of nanoseconds. At 25kV/µs minimum, the ADUM4402ARWZ handles most industrial switching edges up to several hundred volts per microsecond; if your design runs GaN or SiC with sub-10ns switching edges, you need a part with higher CMTI. The rise/fall time of 2.5ns typical is consistent with the 1Mbps data rate — edge rates are not the limiting factor here. ## Temperature range and supply — industrial fit The 16-SOIC wide-body package (7.50mm width) provides the creepage distance needed to sustain the 5000Vrms rating; the narrow-body SOIC-16 would not pass the same isolation test. The part is a standard production item in the iCoupler portfolio, not a phase-out or NRND candidate. For new designs, it is a safe choice with no imminent supply discontinuity.","metaTitle":"ADUM4402ARWZ iCoupler Digital Isolator, 5000Vrms, 1Mbps","metaDescription":"ADUM4402ARWZ general-purpose 4-channel digital isolator with magnetic coupling, 5000Vrms isolation, 1Mbps data rate, 25kV/µs CMTI.

Both are 4-channel, 1Mbps, 5000Vrms iCoupler parts in the same package. The ADUM4401 is a drop-in replacement only if your signal direction map matches 3 inputs on Side 1 and 1 on Side 2.
