ADUM4154BRIZ-RL
Digital Isolator CMOS 7CH 17MHz 20Pin SOIC W T/R
Product Details
The ADuM4154 is an SPIsolator™ digital isolator optimized for a serial peripheral interface SPI that includes support for up to four slave 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 of up to 17 MHz.
The ADuM4154 isolator also provides a slave select multiplexing system that allows up to four slave devices to be serviced from one isolator. When a target slave is selected, the slave select signal propagates to the desired output with low propagation delay, allowing tight timing control. The isolated SSx is addressed through a 250 kbps low speed, 2-channel address bus, allowing the target slave device to be changed in as little as 2.5 μs.
