DESCRIPTION
The PCA9516 is a BiCMOS integrated circuit intended for
application in I
While retaining all the operating modes and features of the I
system, it permits extension of the I
(SDA) and the clock (SCL) lines, thus enabling five buses of 400 pF.
The I
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.
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.
