That 2/1 split fits common sensor-to-controller links where a pair of data lines (SPI MOSI/SCLK, for instance) cross the barrier one way and a single status or interrupt line comes back. The part is rated for 150 Mbps data rate with 13 ns max propagation delay each way, so it keeps up with fast serial buses without adding jitter. ## 5000 Vrms and 75 kV/µs CMTI — why these numbers matter in a switching environment The 5000 Vrms isolation rating qualifies this part for reinforced insulation in medical, industrial, and grid-tied applications where a fault must not cross the barrier. The 75 kV/µs common-mode transient immunity (CMTI) is the spec that actually bites in a switching power supply or motor drive: fast GaN or SiC edges can couple noise across a weak isolator and corrupt data. The ADUM231E1BRIZ's CMTI rating means it rejects those transients cleanly, so the controller side doesn't see false edges. Pulse-width distortion is held to 3 ns max, and rise/fall times are 2.5 ns typical — tight enough that the signal integrity budget stays on your side. ## Active, ROHS3, and available — no LTB headache It is ROHS3 compliant, which clears it for EU and global markets without an exemption hunt.","metaTitle":"ADUM231E1BRIZ iCoupler 3-Ch Digital Isolator, 5000Vrms","metaDescription":"ADI ADUM231E1BRIZ 3-channel unidirectional digital isolator with 5000Vrms isolation, 150Mbps data rate, 75kV/µs CMTI, -40°C to 125°C.
