The chip seems to be the same as four 74HC595 or TPIC6x595 shift registers in a row.
Maybe wise to get some experience with a 595 and LEDs before using this chip.
Comparing datasheets will tell you if CLK/DATA/etc. logic is the same or opposite.
Leo..
Do you need to use that for its high voltage open-drain outputs ?
For clocking data to it, have a look at: shiftOut() reference and see the shiftOut Tutorial.
That device looks similar to the 74HC595, clk looks like it's falling rather than rising edge but that should not matter when using shiftOut().
