ADUM3154BRSZ-RL7

ADUM3154BRSZ-RL7 is an SPIsolator™ digital isolator optimized for a serial peripheral interface (SPI) that includes support for up to four server devices. Based on the Analog Devices, Inc., iCoupler® chip scale transformer technology, the low propagation delay and jitter in the CLK, MO/SI, MI/SO, and active-low SS SPI bus signals support SPI clock rates of up to 17MHz. This isolator also provides a server select multiplexing system that allows up to four server devices to be serviced from one isolator. When a target server is selected, the server select signal propagates to the desired output with low propagation delay, allowing tight timing control. It is approved by UL recognition per UL 1577 3750V rms for 1 minute, CSA component acceptance notice 5A, VDE certificate of conformity, DIN V VDE V 0884-10 (VDE V 0884-10):2006-12, VIORM = 565V peak. It is used in applications such as industrial programmable logic controllers (PLCs), sensor isolation.
