MAX14851AEE+

MAX14851 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 high channel density. 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 channel is open-drain, each capable of data rates from DC to 2Mbps. Independent 3.0V to 5.5V supplies on each side of the isolator also make it suitable for use as a level translator. It can be used for isolating SPI buses, I²C buses, RS-232, RS-485/RS-422 buses, and general-purpose isolation. Application includes industrial control systems, I²C, SPI, SMBus, PMBus™ Interfaces, isolated RS-232, RS-485/RS-422, telecommunication systems, battery management, medical systems.
