3. The connection circuitry always regulates its output to a higher voltage than its input. The magnitude of this offset voltage as a function of
4. Guaranteed by design, not production tested.
5. C
6. Enable time is from power-up of V
7. Idle time is from when SDAx and SCLx are HIGH after enable time has been met.
