DESCRIPTION

The LTC®4332 is a point-to-point rugged SPI extender

designed for operation in high noise industrial environments

over long distances. Using a ±60V fault protected

differential transceiver, the LTC4332 can transmit SPI data,

including an interrupt signal, up to 2MHz over two twisted

pair cables. The extended common mode range and high

common mode rejection on the differential link provides

tolerance to large ground differences between nodes.

The LTC4332 provides a control interface using a separate

slave select for configuration and fault monitoring.
