DESCRIPTION
The PCA9515 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 two buses of 400 pF.
The I
devices and bus length. Using the PCA9515 enables the system
designer to isolate two halves of a bus, thus more devices or longer
length can be accommodated. It can also be used to run two buses,
one at 5 V and the other at 3.3 V or a 400 kHz and 100 kHz bus,
where the 100 kHz bus is isolated when 400 kHz operation of the
other is required.
