LTC4331 Datasheet I2c Slave Device Extender Over Rugged Differential Link

Manufacturer: Analog Devices

Overview: LTC4331 I2C Slave Device Extender Over Rugged Differential Link.

General Description

The LTC®4331 is a point-to-point SMBus compatible I2C slave device extender designed for operation in high noise industrial environments.

Using a ±60V fault protected differential transceiver, the LTC4331 can extend an I2C/ SMBus bus, including SMBALERT and a control signal, over a single twisted pair differential link up to 1200m.

With an extended common mode operating range the solution provides tolerance to large ground differences between nodes.
