PCA9516A
5-channel I

C hub

2004 Sep 29
DESCRIPTION
The PCA9516A is a CMOS integrated circuit intended for application
in I
2
C and SMBus systems.
While retaining all the operating modes and features of the I
2
C
system, it permits extension of the I
2
C-bus by buffering both the data
(SDA) and the clock (SCL) lines, thus enabling five buses of 400 pF.
The I
2
C-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 where the 100 kHz bus is isolated
when 400 kHz operation of the other bus is required.
Two or more PCA9516As cannot be put in series.
The
PCA9516A design does not allow this configuration. Since there is
no direction pin, slightly different “l(fā)egal” low voltage levels are used
to avoid lock-up conditions between the input and the output of each
repeater in the hub. A “regular LOW” applied at the input of a
PCA9516A will be propagated as a “buffered LOW” with a slightly
higher value on all the enabled outputs. When this “buffered LOW” is
applied to another PCA9515A, PCA9516A, or PCA9518 in series,
the second PCA9515A, PCA9516A, or PCA9518 will not recognize
it as a “regular LOW” and will not propagate it as a “buffered LOW”
again. The PCA9510/9511/9513/9514 and PCA9512 cannot be used
in series with the PCA9515A, PCA9516A, or PCA9518 but can be
used in series with themselves since they use shifting instead of
static offsets to avoid lock-up conditions.

The maximum system operating frequency may be less than 400 kHz because of the delays added by the repeater.
