The MAX14483 is a 6-channel, 3.75kVRMS digital galvanic isolator using Maxim’s proprietary process technology. 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 wire ORed with error outputs from other devices. In addition, an auxiliary channel (AUX) is available for passing timing or control signals from the master side to the slave side and power monitors (SAA, SBA) are provided for both power domains to signal if the opposite side of the isolator is ready for operation. Independent 1.71V to 5.5V supplies on each side of the isolator also make the device suitable for use as a level translator. The MAX14483 has an isolation rating of 3.75kVRMS for 60 seconds and is available in a 20-pin SSOP package with 5.5mm of creepage and clearance. The package material has a minimum comparative tracking index (CTI) of 400V, which gives it a group II rating in creepage tables. The MAX14483 is rated for operation at ambient temperatures of -40°C to +125°C.
