This avoids the bus-turnaround overhead of bidirectional isolators and simplifies firmware timing. The 2.5ns typical rise/fall time and 14ns max propagation delay leave healthy margin for SPI timing closure at 34 Mbps. ## Industrial temperature range and common-mode transient immunity The minimum common-mode transient immunity of 25kV/µs means it holds data integrity through fast voltage transients from switching power stages or relay contact arcs — a spec that matters more than the headline isolation voltage in noisy environments. ## Supply voltage range and package The part operates from 3V to 5.5V on each side independently, so it can bridge a 3.3V MCU domain to a 5V sensor or actuator side without a level shifter. It comes in a 20-SSOP package with a 5.30mm body width — a common footprint for multi-channel isolators, but verify the land pattern against your layout if migrating from an SOIC-16 part.","metaTitle":"ADUM3152BRSZ SPI Digital Isolator, 34Mbps, 3750Vrms, 7 Ch","metaDescription":"ADI ADUM3152BRSZ SPI digital isolator: 7 unidirectional channels, 34Mbps data rate, 3750Vrms isolation, 20-SSOP.
