MAX14850ASE+

MAX14850ASE+ is a six-channel digital isolator utilizing Maxim’s proprietary process technology, whose monolithic design provides a compact and low-cost transfer of digital signals between circuits with different power domains. The technology enables low power consumption and stable high-temperature performance. The four unidirectional channels are each capable of DC to 50Mbps, with two of the four channels passing data across the isolation barrier in each direction. The two bidirectional channels are open-drain, each capable of data rates from DC to 2Mbps. Independent 3V to 5.5V supplies on each side of the isolator also make it suitable for use as a level translator. It is used in applications such as industrial control systems, I²C, SPI, SMBus, PMBus™ Interfaces, isolated RS-232, RS-485/RS-422, telecommunication systems, battery management, medical systems.
