NXP P82B715PN 芯片, 总线扩展器
**General description**
The P82B715 is a bipolar IC intended for application in I2C-bus and derivative bus systems. While retaining all the operating modes and features of the I2C-bus it permits extension of the practical separation distance between components on the I2C-bus by buffering both the data SDA and the clock SCL lines.
**Features**
\- Dual, bidirectional, unity voltage gain buffer with no external directional controlrequired
\- Compatible with I2C-bus and its derivatives SMBus, PMBus, DDC, etc.
\- Logic signal levels may include but not exceed both supply and ground
\- Logic signal input voltage levels are output without change and are independent of VCC
\- ×10 impedance transformation, but does not change logic voltage levels
