V = 849 V peak IORM APPLICATIONS Industrial programmable logic controllers (PLCs) Sensor isolation GENERAL DESCRIPTION 1 The ADuM4154 is an SPIsolator digital isolator optimized for Table 1. Related Products a serial peripheral interface (SPI) that includes support for up to Product Description four slave devices. Based on the Analog Devices, Inc., iCoupler ADuM3150 3.75 kV, high speed, clock delayed chip scale transformer technology, the low propagation delay and SPIsolator SS jitter in the CLK, MO/SI, MI/SO, and SPI bus signals support ADuM3151/ADuM3152/ 3.75 kV, multichannel SPIsolator SPI clock rates of up to 17 MHz. ADuM3153 ADuM3154 3.75 kV, multiple slave SPIsolator The ADuM4154 isolator also provides a slave select multiplexing ADuM4150 5 kV, high speed, clock delayed system that allows up to four slave devices to be serviced from SPIsolator one isolator. When a target slave is selected, the slave select ADuM4151/ADuM4152/ 5 kV, multichannel SPIsolator signal propagates to the desired output with low propagation ADuM4153 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 s. 1 Protected by U.S. Patents 5,952,849 6,262,600 6,873,065 and 7075329.
