Tool/software:
Dear Specialists,
My customer has questions regarding SN74LVC2G14.
I would be grateful if you could advise.
---
(1) The data sheet says that it has a "Back-Drive Protection" function.
Could you please let me know what is this function in detail?
Generally, Back-Drive Protection is a function that disconnects the input and output from the outside by making them high impedance, and is thought to be achieved with a low Ioff (10μAmax).
(2) I understand that the input of the SN74LVC2G14 is originally high impedance.
-Is this understanding correct?
-Is there a circuit that actually disconnects the input voltage so that it does not affect the internal circuit?
- Could you please let me know what the input circuit be like.
(3) When the output becomes high impedance,
-I understand that both the Hi output circuit and the Lo output circuit are turned off.
Is this understanding correct?
(4) Could you please tell me the conditions under which "Back-Drive Protection" and "Partial-Power-Down" occur (partial-power-down applications?)

I appreciate your great help in advance.
Best regards,
Shinichi
