What voltage do the BE bus enable (active low) pins need to be set to when not active low?
The SEL pin is specified what voltage it needs but not this pin. I've looked across data sheets on multiple level translators to try and figure this out.
When not active, you may set the BE pin of the ADG3247 to a minimum of:
This information can be seen on page 2 Specifications Section of the ADG3247 Datasheet, Input High Voltage. See figure below.
Let me know if this helps.
