The PCA9516 is a BiCMOS integrated circuit intended for
application in I2C and SMBus systems.
While retaining all the operating modes and features of the I2C
system, it permits extension of the I2C-bus by buffering both the data
(SDA) and the clock (SCL) lines, thus enabling five buses of 400 pF.
The I2C-bus capacitance limit of 400 pF restricts the number of
devices and bus length. Using the PCA9516 enables the system
designer to divide the bus into five segments off of a hub where any
segment to segment transition sees only one repeater delay.
