MAX14931EASE+

MAX14931EASE+ is a 4-channel digital isolator. 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. This device has independent 1.71V to 5.5V supplies on each side of the isolator also makes the devices suitable for use as level translators. It is approved by UL according to UL1577, cUL according to CSA bulletin 5A, VDE 0884-10. It is used in applications such as fieldbus communications for industrial automation, isolated SPI, RS-232, RS-485/RS-422, general multichannel isolation applications, battery management, medical systems.
