Описание

The P82B715 is a device for buffering highly-capacitive I2C bus systems, and it supports bidirectional data transfer through the I2C bus. The P82B715 buffers both the serial data (SDA) and serial clock (SCL) signals on the I2C bus and allows for extension of the I2C bus, while retaining all the operating modes and features of the I2C system. For all available packages, see the orderable addendum at the end of the data sheet.

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 Low-Cost Twisted-Pair Cables
