In Datasheet P18 table 19 : Truth table.
When VDDO is Unpowered, Vox Output is Hi-Z.
So I want to know that If VDDO voltage is slowly increasing or decrease, how much voltage dose it keep Hi-Z?
Because same voltage source and line device has UVLO at 2.5V. I don't want to input signal to the device at power off.
And Dose it have a hysteresis?
