Two channels are configured from Side 1 to Side 2, and one channel runs from Side 2 to Side 1 — a 2/1 unidirectional split that suits applications like isolated SPI where you need MISO, MOSI, and a clock or chip-select in the opposite direction. The part handles data rates up to 10Mbps with 50ns max propagation delay and 5ns pulse-width distortion, so it fits UART, SPI, and general-purpose logic isolation without timing margin headaches. The 3750Vrms isolation rating is the withstand voltage for basic insulation. In a motor drive or industrial PSU, that covers the reinforced isolation requirement for 300V working voltage systems. The 25kV/µs common-mode transient immunity (CMTI) is the spec that matters when you place this isolator between a noisy power stage and a sensitive controller — fast-switching SiC or IGBT edges can couple several kV/µs across the barrier, and if the isolator's CMTI is too low, data corrupts or the output latches. At 25kV/µs minimum, this part handles the transients from a typical 600V/30A inverter leg without bit errors. Both sides of the isolator run from a single 2.7V to 5.5V supply, so you can interface a 3.3V MCU to a 5V peripheral without a level shifter — the part handles the voltage translation internally. The 16-SOIC wide-body package (7.50mm body width) gives the creepage distance needed for the 3750Vrms rating.","metaTitle":"ADUM1311BRWZ-RL iCoupler Digital Isolator, 3750Vrms, 3-Ch","metaDescription":"ADI ADUM1311BRWZ-RL 3-channel digital isolator with magnetic coupling, 3750Vrms isolation, 10Mbps data rate, -40°C to 105°C.
