MAX14434FAWE+

MAX14434FAWE+ is a four-channel, fast, low-power, 5kVRMS digital isolator. This device transfers digital signals between circuits with different power domains while using as little as 0.58mW per channel at 1Mbps with a 1.8V supply. It offers all three possible unidirectional channel configurations to accommodate any 4-channel design, including SPI, RS-232, RS-485, and digital I/O applications. Applications include isolated SPI interface, fieldbus communications for industrial automation, isolated RS-485/RS-422, CAN, battery management, and medical systems.
