n 4mm × 5mm 20-Lead QFN Package 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. n The LTC4332 provides a control interface using a separate
slave select for configuration and fault monitoring.
