The 4/0 input-to-output channel arrangement means all four channels run from side 1 to side 2 — no reverse-direction channels. This part sits in industrial automation, motor drives, medical equipment, and any isolated data interface where you need to move digital signals across a safety barrier without an isolated power supply on the secondary side. ## Package and mounting The 90 Mbps data rate covers SPI, UART, and parallel bus isolation up to about 45 MHz clock. The 25 kV/µs common-mode transient immunity (CMTI) is the spec that matters in noisy environments — motor drives, inverter legs, and industrial fieldbus where fast voltage transients couple across the barrier. If the CMTI is too low, the output glitches or latches. At 25 kV/µs minimum, this part handles the dV/dt from a typical IGBT switching leg without hiccup. Rise and fall times are a symmetric 2.5 ns typical, which keeps signal integrity clean on short PCB traces. ## Supply range and temperature — field-fit check No isolated power output — this is a pure signal isolator; you supply Vdd on both sides separately.","metaTitle":"ADUM3400CRWZ iCoupler Digital Isolator, 90 Mbps, 2500 Vrms","metaDescription":"ADI ADUM3400CRWZ general-purpose digital isolator: 4-ch unidirectional, 90 Mbps data rate, 2500 Vrms isolation, 25 kV/µs CMTI, -40 to 105°C.
