ADUM3154BRSZ

ADUM3154 is a SPIsolator™ digital isolator optimized for a serial peripheral interface (SPI) that includes support for upto four secondary devices. Based on the Analog Devices, Inc., iCoupler® chip scale transformer technology. This device isolator also provides a secondary select multiplexing system that allows up to four secondary devices to be serviced from one isolator. When a target secondary device is selected, the secondary 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 widely used in application such as industrial programmable logic controllers (PLCs), sensor isolation etc.
