MAX14483AAP+

MAX14483AAP+ is a 6-channel, 3.75KVRMS digital galvanic isolator. The six signal channels are individually optimized for SPI applications and include very low propagation delay on the SDI, SDO, and SCLK channels. The SDO channel’s tri-state control is enabled by the active-low CS input as well as a second enable control input pin (active-low SDOEN), allowing a single MAX14483 to isolate multiple SPI devices. To simplify system design, an open-drain active-low FAULT output can be wired with error outputs from other devices. Independent 1.71V to 5.5V supplies on each side of the isolator also make the device suitable for use as a level translator. Typical applications include programmable logic controllers, industrial automation, process automation, building automation, robotics, general SPI-bus isolation.
