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.

Supports up to 17 MHz SPI clock speed
4 high speed, low propagation delay, SPI signal isolation channels
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
Applications
Industrial programmable logic controllers (PLCs)
