Please refer to this FAQ on unused pins.

Since the input pins have pulldown, it will be at gnd and hence ok. The output pins can be left floating.

Hi Shreyas,

Thank you for your answer.

Additionally, the customer is asking what is the operating current of the SN74LVC15A-Q1.

Can you provide the data for them?

Thanks,

Sam Lee
