P82B715 - I2C bus extender

Description

The P82B715 is a device for buffering highlycapacitive I2C bus systems, and it supports bidirectional data transfer through the I2C bus.

Features

  • 1 Operating Power-Supply Voltage Range of 3 V to 12 V.
  • Supports Bidirectional Data Transfer of I2C Bus Signals.
  • Allows Bus Capacitance of 400 pF on Main I2C Bus (Sx/Sy Side) and 3000 pF on Transmission Side (Lx/Ly Side).
  • Dual Bidirectional Unity-Voltage-Gain Buffer With No External Directional Control Required.
  • Drives 10× Lower-Impedance Bus Wiring for Improved Noise Immunity.
  • Multi-Drop Distribution of I2C Signals Using LowCost Twisted-Pair.
