We prefer to use SN74LV125AQRGYR-Q1 for our application. Could you please advise regarding the following three questions?

Hi Gary,
Unused inputs need to be connected to either VCC or GND, whichever is more convenient. Unused outputs should be left disconnected. We have an FAQ that discusses this topic specifically: (+) [FAQ] How do I terminate any unused channels of a logic device? - Logic forum - Logic - TI E2E support forums
As for the highlighted text, this is referencing the "Ioff" feature of the device, also called "Partial power-down protection." This feature puts the outputs of a device into the high-impedance state when the supply voltage is at 0V. Ioff specifies the leakage current into any I/O pin during this state and is specified in the electrical characteristics table here:
