What this isolator does on your board
The Analog Devices ADUM160N0BRZ-RL7 is a 6-channel, unidirectional digital isolator using magnetic coupling to transfer digital signals across a 3000 Vrms galvanic isolation barrier. It's a general-purpose part meant for breaking ground loops, protecting low-voltage logic from high-side transients, and meeting safety isolation requirements in industrial, medical, and telecom equipment.
Speed and timing — what 150 Mbps and 13 ns propagation delay mean
At 150 Mbps, this isolator keeps up with fast serial links. The 13 ns max propagation delay (both tpLH and tpHL) and 4.5 ns pulse-width distortion mean the output pulse width stays close to the input — important for maintaining duty cycle on PWM signals or clock lines. Rise and fall times are a tight 2.5 ns typical, so edge rates are clean enough for most digital loads without excessive ringing.
Common-mode transient immunity — 75 kV/µs
The 75 kV/µs minimum common-mode transient immunity (CMTI) is the spec that matters when this isolator sits on a motor drive, inverter, or any power stage where the ground on one side can jump hundreds of volts in a microsecond. A lower CMTI part would glitch or latch, corrupting data. This rating means the ADUM160N0BRZ-RL7 holds the output state through those fast transients — a key reason to pick it over optocouplers or older digital isolators.

Lifecycle and sourcing
ADI lists this part as Active. If you're qualifying for production, the active status means you can design it in without an obsolescence risk on the horizon.
