接口-信号缓冲器、中继器 I2C Bus Extender
DESCRIPON
The P82B715 is a bipolar device intended for I2C bus systems applications and supports bidirectional data transfer via the I2C bus. The P82B715 buffers both the serial data SDA and serial clock SCL signals on the I 2C bus and allows for extension of the I2C bus, while retaining all the operating modes and features of the I2C system.
