Data Sheet ADuM4154 5 kV, 7-Channel SPIsolator Multiple Slave, Digital Isolator for SPI FEATURES FUNCTIONAL BLOCK DIAGRAM ► Supports up to 17 MHz SPI clock speed ► 4 high speed, low propagation delay, SPI signal isolation chan- nels ► Supports up to 4 slave devices ► 20-lead SOIC_IC package with 8.3 mm creepage ► High temperature operation: 125°C ► High common-mode transient immunity: >25 kV/µs ► Safety and regulatory approvals ► UL recognition per UL 1577 ► 5000 V rms for 1 minute SOIC long package ► CSA certification per IEC 62368-1, IEC 61010-1, and IEC 60601-1 ► VDE certificate of conformity ► DIN V VDE V 0884-10 (VDE V 0884-10):2006-12 ► VIORM = 849 V peak Figure 1. APPLICATIONS ► Industrial programmable logic controllers (PLCs) ► Sensor isolation GENERAL DESCRIPTION The ADuM41541 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.
