MAX14850:Six-Channel Digital Isolator

Industry's First Monolithic 600VRMS Digital Isolator

The MAX14850 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 and each is 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 MAX14850 can be used for isolating SPI busses, I2C busses, RS-232, RS-485/RS-422 busses, and general-purpose isolation. When used as a bus isolator, extra channels are available for power monitoring and reset signals. The MAX14850 is available in a narrow body,16-pin SOIC (10mm x 4mm) package (for which an evaluation kit is available) and 16-pin QSOP (3.9mm x 4.94mm) package. The packages are specified over the -40°C to +125°C automotive temperature range.
