That figure tells you the isolator can reject fast voltage transients between its two ground domains — exactly what you get when a motor drive or a half-bridge power stage switches. If the CMTI is too low, the output glitches or latches, corrupting the data stream. At 75 kV/µs this part stays clean alongside GaN or SiC switching stages running at high dv/dt. The 4/0 input-side/side-2 configuration means all four channels are oriented the same direction — all inputs on side 1, all outputs on side 2. ## Active lifecycle and RoHS compliance No isolated power converter is integrated; you supply Vdd1 and Vdd2 separately on each side of the barrier.","metaTitle":"ADUM140E1BRZ iCoupler Digital Isolator, 150 Mbps, 3000 Vrms","metaDescription":"ADUM140E1BRZ 4-channel digital isolator with 150 Mbps data rate, 3000 Vrms isolation, 75 kV/µs CMTI.
