The ADUM140E1BRZ-RL7: ROHS3 compliant per the listing, which simplifies EU market compliance.
The 3000Vrms isolation rating is the safety barrier spec: it tells you this part can withstand a 3 kV RMS potential between the input and output sides for one minute, which covers reinforced insulation requirements in many industrial and medical power-supply designs.
150Mbps data rate and 13ns propagation delay
Data rate is 150Mbps. Propagation delay is 13ns max, pulse-width distortion is 3ns max.
Four unidirectional channels, all same-direction
The channel configuration is 4/0 — all four channels run in the same direction, from Side 1 to Side 2. If your design needs bidirectional isolation or a mix of input and output channels, the ADUM142E1BRZ-RL7 (2/2 split) is the sibling to look at.
The 1.7V to 5.5V supply range covers the common digital logic rails — 1.8V, 2.5V, 3.3V, and 5V — so the same part can bridge between different voltage domains without a level shifter.
