Look again, because I don't see "two pin[ s ] grounded".
Is this a language issue or have you misunderstood?
Since you could find the datasheet to attach, I can only hope you have read it.
I am starting to forget the question...
I don't think we've ever gotten far enough to even have a coherent question framed.

Round and round.

that was my mistake
you did connected two pin together because we just need both pin high or low.

When the signal is LOW, existing data is retained in
a hold (“do nothing”) mode.
when the select pin is HIGH, data is transferred to the Q0 to Q3 outputs respectively,
