The MAX14935BAWE+ is a four-channel, 5KVRMS digital isolator in 16 pin WSOIC package. It transfers digital signals between circuits with different power domains at ambient temperatures up to +125°C. It offers all three possible unidirectional channel configurations to accommodate any four-channel design, including SPI, RS232, RS485 and large digital IO modules. The device is available with data rates from DC up to 25Mbps and default high configuration. The default is the state an output goes to when its input is unpowered. Independent 1.71V to 5.5V supplies on each side of the isolator also make the device suitable for use as level translators. Typical applications include field-bus communications for industrial automation, isolated SPI, RS232, RS485/RS422, general multichannel isolation applications, battery management and medical systems.
