ABSOLUTE MAXIMUM RATINGS
Note 1:
Ratings" may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any other conditions above those indicated
in the operation sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may effect the device reliability.

Test feature
If the TEST pin is pulled low, the status of all 24 LED's are output at pin DOUT in
3 groups of 8 status bits each, with a start bit and a stop bit added. The data rate
of this status word is equal to the input data rate (i.e. CLK) devided by 8.
The three data word that are serially output at DOUT each contain 11-bit. This
means that bit 10 is not used in each case. The words therefore contain a start bit,
8 LED status bits (1 for off, 0 for on). 1 unused bit, and a stop bit. The three groups
are output consecutively in the following order: first LED's 1 to 8, then 9 to 16, and
then 17 to 24.
