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
the pull-up resistor and V
CC
voltage is shown in the Typical Performance Characteristics section.
4. Guaranteed by design, not production tested.
5. C
= total capacitance of one bus line in pF.
6. Enable time is from power-up of V
and V
≥
2.7 V to when idle or stop time begins.
7. Idle time is from when SDAx and SCLx are HIGH after enable time has been met.
