Description

DESCRIPTION
   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 of PCA9516 into five segments off of a hub where any segment to segment transition sees only one repeater delay. It can also be used to run different buses at 5 V and 3.3 V or 400 kHz and 100 kHz buses where the 100 kHz bus is isolated when 400 kHz operation of the other bus is required.
