CD74HC107: About unused pins

Hi,

This device is 2 ch, but I only use 1 ch.
I think that the setting of unused ch is red frame in the table below.
Is my opinion correct?

Best regards,

    Hello,

    You can tie all inputs of the second flip-flop low (R\, CP\, J, K), and then leave the outputs floating (Q, Q\). The flip-flop will be permanently set to having Q = L and Q\ = H, but since the outputs won't be connected to anything, they won't drive any current.
