The 150Mbps data rate handles high-speed serial interfaces such as SPI without adding significant propagation delay — 13ns max per channel. The 150Mbps data rate is fast enough for SPI clock rates up to 75 MHz in half-duplex mode, or full-duplex SPI with two channels per direction. The 75kV/µs common-mode transient immunity is the spec that matters in motor-drive and inverter environments — fast-switching SiC or IGBT stages can inject several kV/µs across the isolation barrier, and this part holds its output state through those edges. Pulse-width distortion is held to 3ns max, which keeps the duty cycle intact for PWM or timing-sensitive links. ## Package and temperature grade for the environment Housed in a 16-SOIC package with 3.90mm body width, surface-mount only.","metaTitle":"ADUM140E0BRZ-RL7 iCoupler Digital Isolator, 150Mbps","metaDescription":"ADUM140E0BRZ-RL7 iCoupler 4-channel digital isolator, 150Mbps data rate, 3000Vrms isolation, -40°C to 125°C.

With a 150Mbps data rate and 13ns propagation delay, this part can isolate SPI buses up to 75 MHz in half-duplex mode, or full-duplex SPI using two channels per direction.
