I have some question about partial power down and vcc isolation feature
Q1: I'm planning to use translator in a system with two different voltage levels.
Vcca will always be active. Vccb will turn on and off from time to time.
I will make the OE pin high before turning off the Vccb
Is it ok to use it such a way?
Q2: When Vcca is active-Vccb is turned off, can I leave the Vcca input/output ports floating?
Q3: Does using this way for a long time affect the device in terms of reliability?
