Hello,

 
Could someone please clarify what the truth table for ADG858 switches A and B looks like when VDD is either at 0V or not connected, and IN1 and IN2 are either Low or High?

 
Thanks.

    Hi,
    
 
    When there is no VDD present, there can be no guarantee to what the state of the switch will be.
    
 
    If you need the switch to be in a guaranteed state when there is no supply present then let me recommend the ADG4612. In this part the switches are guaranteed off with no power supply is present.
