6-Channel SPI Digital Isolator

6-Channel SPI Digital Isolator

Maxim Integrated has released the MAX14483 SPI digital isolator ICs, which feature six isolated channels individually optimized for SPI applications. They provide very low propagation delay (10ns typical) on the SDI, SDO and SCLK channels. The SDO channel’s tri-state control is enabled by the CS input and a second enable control input pin (SDOEN), allowing a single device to isolate multiple SPI devices. These 3.75kVRMS digital galvanic isolators are housed in 20-pin SSOP packages and have an operational temperature range of -40°C to 125°C, which makes them suitable for use in industrial, process, and building automation applications, as well as robotics and programmable logic controllers.
