P82B96D by Texas Instruments

400-kHz Fast I2 C Bus Operation Over at Least 20 Meters of Wire
Can Interface Between I2 C Buses Operating at Different Logic Levels (2 V to 15 V)
ESD Protection Exceeds JESD 22
Interface With Optoelectrical Isolators and Similar Devices That Need Unidirectional Input and Output Signal Paths by Splitting I2 C Bus Signals Into Pairs of Forward (Tx/Ty) and Reverse (Rx/Ry) Signals
Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II
Longer Cables by allowing bus capacitance of 400 pF on Main Side (Sx/Sy) and 4000 pF on Transmission Side (Tx/Ty)
Operating Power-Supply Voltage Range of 2 V to 15 V
Outputs on the Transmission Side (Tx/Ty) Have High Current Sink Capability for Driving Low- Impedance or High-Capacitive Buses
Part Information

RoHS Compliant
The P82B96 device is a bus buffer that supports bidirectional data transfer between an I2C bus and a range of other bus configurations with different voltage and current levels. One of the advantages of the P82B96 is that it supports longer cables/traces and allows for more devices per I2C bus because it can isolate bus capacitance such that the total loading (devices and trace lengths) of the new bus or remote I2C nodes are not apparent to other I2C buses (or nodes). The restrictions on the number of I2C devices in a system due to capacitance, or the physical separation between them, are greatly improved. The device is able to provide galvanic isolation (optocoupling) or use balanced transmission lines (twisted pairs), because separate directional Tx and Rx signals are provided. The Tx and Rx signals may be connected directly (without causing bus latching), to provide an bidirectional signal line with I2C properties (open-drain driver). Likewise, the Ty and Ry signals may also be connected together to provide an bidirectional signal line with I2C properties (opendrain driver). This allows for a simple communication design, saving design time and costs.
