APPLICATION INFORMATION
For applications with a large number of LEDs,
several CAT310 drivers can be daisy chained.
The serial data output pin (SOUT) of the first
driver is connected to the second driver data
input pin (SIN). This sequence is repeated until
the last driver is linked. All drivers are controlled
by the same clock signal. Figure 1 shows an
example with three CAT310 devices driving a
total of 30 LEDs in parallel. The controller
transmits the serial data sequentially through the
CAT310 devices. For N drivers connected in
cascade, after 10 x N clock pulses, the data are
latched with one single XLAT transition.
