Welcome, @Håvard Kalliainen, to the community!
Well, LED2472G is a shift register, but it can only be used as such to a limited extent: the individual outputs (bits) are actually constant-current LED drivers, so they are not really suitable for logic purposes. But of course you can control the loads connected to the individual outputs logically in the same way as a shift register. Only the serial output is directly comparable with a classic shift register.
However, one could imagine using LED2472G to drive 30mA relays, even if this does not correspond to the original purpose. But you must not forget the usual free-wheeling diodes, which due to the unspecified avalanche energy should better be Schottky diodes, because only they are fast enough. Even ultra-fast diodes with a blocking time of 10...20ns are probably too slow not to damage the respective LED driver - at least nobody guarantees that.
Does it answer your question?
