Hi Team,
about SN74HC00:
If VCC in not powered up, but input side have 5V input at logic input. Will there be some voltage on VCC?
That is: is there any leakage path from logic input to VCC?

Yes, HC devices have clamping diodes; see [FAQ] Can the input voltage (Vi) to my logic device be higher than the supply voltage (Vcc)?
