you asked specifically can I use this as a multiple... basic reading skills and the ability to click on a link provide the answer!
if you'd asked:
does this
< Buffered multiple outputs
< Threads into three buffered outputs;
< source - the product description
mean I can use it as a multiple?
it would at least look like you'd done some research and don't just want to be spoon fed the answer!!!
so the answer is yes - you can, but if you want it for triggers, gates, cv and audio (and not v/oct) then it may be overkill - you just need a passive mult for those - buffered is only needed for v/oct (and in some cases where an output is expecting a buffered input - some make noise modules)
TBH - if what you want is a multiple - just buy a multiple - this appears to be massive overkill just for a mult!!!
or build one - really easy, if you can solder - if you can't it's really easy to learn - and a passive mult is a good place to start - and it's a very handy skill to have in modular synthesis - there are plenty of instruction videos on youtube - AISynthesis is great for beginner kits - like mults

Utility modules are the dull polish that makes the shiny modules actually shine!!!
