It delivers a 150 Mbps data rate across a 3750 Vrms isolation barrier, making it a fit for breaking ground loops and protecting low-voltage logic in industrial fieldbus, motor-drive interfaces, and isolated SPI links. ## What the 150 Mbps and 13 ns propagation delay mean for your bus At 150 Mbps the ADUM142D0BRWZ can clock a full-speed SPI bus, an LVDS-equivalent serial link, or a parallel data bus running at tens of megahertz without adding a cycle of latency. The 13 ns max propagation delay (tpLH / tpHL) and 3 ns max pulse-width distortion mean the timing skew between channels stays tight enough that a multi-bit parallel interface does not need a separate deskew circuit. The 2.5 ns typical rise/fall times keep the signal edges clean for the trace lengths typical on an industrial control board. ## 75 kV/µs CMTI — why it matters for motor drives and inverters Common-mode transient immunity of 75 kV/µs (minimum) is the spec that separates an industrial-grade isolator from a benign-signal part. In a variable-frequency drive or an inverter-fed motor, the switching edges on the power stage can couple several kilovolts per microsecond across the isolation barrier. If the isolator's CMTI is too low, those edges corrupt the data on the logic side. The ADUM142D0BRWZ's 75 kV/µs rating covers that transient environment without needing external filtering on every channel. It is ROHS3 compliant. If you are qualifying this isolator into a new design, the active lifecycle means you are not locking into a part that will disappear mid-production.","metaTitle":"ADUM142D0BRWZ iCoupler Digital Isolator, 150 Mbps, 3750 Vrms","metaDescription":"ADUM142D0BRWZ 4-channel digital isolator, 150 Mbps data rate, 3750 Vrms isolation, -40 to 125°C.
