Rated for 150Mbps, it handles high-speed interfaces like SPI, UART, and parallel buses while maintaining galvanic isolation for safety and noise rejection. The wide supply range from 1.7V to 5.5V means it can bridge 1.8V, 2.5V, 3.3V, and 5V logic domains directly — no external level shifters needed on the data lines. ## 75kV/µs CMTI — keeps data clean in noisy environments Common-mode transient immunity of 75kV/µs is the headline robustness figure. In motor-drive or inverter applications where fast-switching IGBTs or SiC FETs slam the ground plane with kilovolt-per-microsecond edges, this rating ensures the output doesn't glitch. Paired with 2.5ns typical rise/fall times and 13ns max propagation delay, timing skew across the 4 channels stays tight enough for synchronous interfaces. The pulse width distortion is max 3ns, so the part maintains signal integrity across temperature extremes — important for PWM or encoder feedback paths where duty-cycle accuracy matters. ## Package and footprint — 16-SOIC narrow body Housed in a 16-SOIC narrow-body package (3.90mm body width), the ADUM140D1BRZ-RL7 shares the same footprint as many other iCoupler 4-channel parts. Surface-mount only. No isolated power output on this variant; it's a pure signal isolator, so each side needs its own supply rail. This is a current-production part suitable for both prototyping and volume production. The iCoupler series is a mature platform with broad second-source compatibility across the ADUM140x family, though no official cross-reference is listed.","metaTitle":"ADUM140D1BRZ-RL7 iCoupler Digital Isolator, 150Mbps","metaDescription":"ADUM140D1BRZ-RL7 iCoupler 4-channel digital isolator, 150Mbps data rate, 3750Vrms isolation, -40°C to 125°C, 16-SOIC.
