LTC4331
I2C Slave Device Extender
Over Rugged Differential Link
FEATURES 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. For EMI sensitive environments, a slew
rate control pin reduces the EMI emitted from the differential link. Up to 1MHz Serial Clock, Fast-mode Plus (Fm+)
Selectable Link Baud Rates Extend I2C Up to
1200m
