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. The 90 Mbps data rate covers SPI, UART, and parallel bus isolation up to about 45 MHz clock. 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.

The ADUM3400CRWZ is the 90 Mbps variant, while the ADUM3400ARWZ is the lower-speed 1 Mbps version. Both are 4-channel unidirectional isolators in the same 16-SOIC wide-body package with 2500 Vrms isolation.
