ADUM4154BRIZ

ADuM4154 is a SPIsolator™ digital isolator optimized for a serial peripheral interface (SPI) that includes support for up to four 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 SS SPI bus signals support SPI clock rates. Safety and regulatory approvals are UL recognition per UL 1577 5000 V rms for 1 minute SOIC long package, CSA component acceptance notice 5A, VDE certificate of conformity, DIN V VDE V 0884-10 (VDE V 0884-10):2006-12, VIORM = 849V peak. Typical application is industrial programmable logic controllers (PLCs), sensor isolation.
