Typically, SPI requires 4 channels total (CS, SCLK, MISO, and MOSI) with 3 forward channels (CS, SCLK, and MOSI) and 1 reverse channel (MISO). Considering this, we recommend the ISO6441, which is our newest generation of digital isolators and suitable for SPI communication. We also have the ISO6741 and ISO7741 which are also great options for SPI. Please view the document below for more information about choosing a digital isolator for SPI communication: Isolating SPI Signals (Rev. A)
