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.
