Question
Does the ADG854 require a certain current to start up, or is there a particular sequence to follow?
Answer
The ADG854 does not need a 50uA to 100uA current for it to power up.Once the ADG854 is power-up, it can pass signals from SxA/SxB to Dx.The correct power-up sequence should be: Vss first, Vdd second, then logicpins, and then input signals.
