Three channels run from Side 1 to Side 2 (SCLK, MOSI, CS), and one channel runs from Side 2 to Side 1 (MISO), matching the standard SPI signal direction. The 2 Mbps data rate limits the SPI clock to roughly 2 MHz — fine for sensor readout, configuration registers, and moderate-throughput ADCs, but not for high-speed serial memory or video links. Propagation delay is 25 ns max, and pulse-width distortion stays under 2 ns, so the clock-to-data skew budget is tight but manageable for most industrial SPI peripherals. ## 3750Vrms isolation and 25 kV/µs CMTI — industrial and medical barrier The 3750Vrms isolation rating meets reinforced insulation requirements for many industrial and medical applications. Common-mode transient immunity of 25 kV/µs minimum means the part holds its logic state through fast switching edges on motor drives, inverters, and isolated power supplies — a spec that matters more than the headline isolation voltage when the barrier sees PWM noise. Rise and fall times are a fast 2.5 ns typical, so keep the trace length short between the isolator and the SPI master or slave to avoid ringing.","metaTitle":"ADUM3154ARSZ-RL7 SPI Digital Isolator, 3750Vrms, 2Mbps","metaDescription":"ADUM3154ARSZ-RL7 SPI digital isolator from ADI's iCoupler series. 3750Vrms isolation, 2Mbps data rate, 4 unidirectional channels, -40°C to 125°C.
