Tool/software:

Is it possible to apply DC5V to the input terminal even when a 3.3V power supply is supplied to the IC?

Yes; see [FAQ] Can the input voltage (Vi) to my logic device be higher than the supply voltage (Vcc)?

Hi Kengo,

Yes, any device with overvoltage tolerant inputs can take an input voltage higher than VCC. For more information please refer to the link that Clemens shared.

Best,

Malcolm
