PCA9516A - 5-channel I2C hub

NXP

Datasheet Details

The PCA9516A is a CMOS integrated circuit intended for application in I2C-bus and SMBus systems..

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 buses at 5 V and 3.3 V or 400 kHz and 100 kHz buses w.
