This specification applies over the full operating temperature range.
The enable time can slow considerably for some parts when temperature is < 20 C.
Delays that can occur after ENABLE and/or idle times have passed.
Guaranteed by design, not production tested.

The connection circuitry always regulates its output to a higher voltage than its input. The magnitude of this offset voltage as a function
of the pull-up resistor and V
