The four channels are split 2/2 across the barrier and run unidirectional, which covers the common case of a microcontroller talking to a gate driver or a sensor interface on the isolated side. At 10 Mbps the part handles SPI clock rates up to 10 MHz and most UART, CAN, or LIN data streams without stretching the pulse width. The max propagation delay is 36 ns in either direction, and pulse-width distortion stays under 3.5 ns, so the timing budget for the rest of the bus is generous. Common-mode transient immunity is rated at 25 kV/µs minimum — that is the spec that matters when the isolator sits between a PWM-driven inverter stage and the control logic. A fast voltage step on the isolated side will not glitch the output if the CMTI is high enough, and 25 kV/µs is well into the territory where motor-drive and automotive traction-inverter noise is rejected. The package is a 16-lead SOIC with the wide 7.50 mm body — the same footprint used across the ADuM340x family, so a board laid out for the standard variant takes the automotive-grade part without a spin. No isolated power is integrated; the part is a pure signal isolator, so each side needs its own local supply rail. ## Active lifecycle and automotive qualification The 'W' in the order code flags the automotive grade — this is the variant qualified per AEC-Q100, so it carries the documented process change and defect-level traceability that production automotive and heavy-equipment programs require. No NRND or last-time-buy notice is in effect as of the current record.","metaTitle":"ADUM3402WBRWZ Digital Isolator, 2500Vrms, 10Mbps","metaDescription":"ADUM3402WBRWZ quad-channel digital isolator with magnetic coupling. 2500Vrms isolation, 10Mbps data rate, -40°C to 125°C.
