The 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 channels are 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. The MAX14851 can be used for isolating SPI buses, I2C buses, RS-232, RS-485/RS-422 buses, and general-purpose isolation. When used as a bus isolator, extra channels are available for power monitoring and reset signals.
The MAX14851 is available in a 16-pin QSOP (3.9mm x 4.94mm) package. The device is specified over the -40°C to +125°C temperature range.
The MAX14851 is a functional replacement for the MAX14850, and shares the same pin configurations as the MAX14850.
