The wide supply range from 1.7V to 5.5V lets it bridge different logic levels directly — no extra level shifter needed. ## 3750Vrms isolation and 75kV/µs CMTI — why they matter The 3750Vrms isolation rating is the spec that drives safety certification — it gives you the creepage distance needed for reinforced insulation in mains-connected equipment. The 75kV/µs common-mode transient immunity (CMTI) is the spec that keeps the data link alive when the other side of the barrier is switching high voltages at high dV/dt, like in a motor-drive inverter or a flyback converter. If the CMTI is too low, the isolator can glitch or latch up, corrupting the signal. This part's 75kV/µs minimum is a strong number for industrial drives; you can run it in a 600V bus environment without worrying about the barrier coupling noise into the logic side. ## Package and mounting The ADUM141E1BRWZ-RL comes in a 16-SOIC wide-body package (7.50mm body width, 0.295\" pitch). That wide body gives the creepage distance needed for 3750Vrms — the narrow SOIC-16 (3.9mm wide) would not pass the same safety spacing. For the rework bench: this is a standard SOIC footprint, easy to hand-solder or remove with hot air. The wide body has more thermal mass than a narrow SOIC, so bump the hot-air temperature 10-15°C above your usual narrow-SOIC profile. ## Sourcing this part for the BOM If you are dual-sourcing, the ADUM141E0BRWZ is a pin-compatible alternative in the same family; the difference is in the default output state on power-up (version has high output on the reverse channel when unpowered). That matters for fail-safe behavior, so check your application's power-up sequence before swapping.","metaTitle":"ADUM141E1BRWZ-RL Digital Isolator, 150Mbps, 3750Vrms","metaDescription":"ADUM141E1BRWZ-RL iCoupler digital isolator: 4 channels, 150Mbps data rate, 3750Vrms isolation, -40 to 125°C.
