Overview

PCA9516A 5-channel I2C-bus hub Rev.
03 — 23 April 2009 Product data sheet 1.
General description The PCA9516A is a CMOS integrated circuit intended for application in I2C-bus and SMBus systems.
While retaining all the operating modes and features of the I2C-bus system, it permits extension of the I2C-bus by buffering both the data (SDAn) and the clock (SCLn) 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 PCA9516A 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.
It can also be used to run different buse...
