P82B715PN中文资料飞利浦数据手册PDF规格书

DESCRIPTION

The 82B715 is a bipolar integrated circuit intended for application in I2C bus systems.

While retaining all the operating modes and features of the I2C system 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.

The I2C bus capacitance limit of 400pF restricts practical communication distances to a few meters. Using one 82B715 at each end of longer cables reduces the cable loading capacitance on the I2C bus by a factor of 10 times and may allow the use of low cost general purpose wiring to extend bus lengths.

FEATURES

• Dual, bi-directional, unity voltage gain buffer

• I2C bus compatible

• Logic signal levels may include both supply and ground

• X10 impedance transformation

• Wide supply voltage range
