MAX14432FASE+

MAX14432FASE+ is a fast, low-power, 4-channel, digital galvanic 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.
