1. This specification applies over the full operating temperature range.
2. I
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
4. Guaranteed by design, not production tested.
5. C
6. SDA_IN/SCL_IN = 0.1 V, SDA_OUT/SCL_OUT through resistor to V
7. Delays that can occur after ENABLE and/or idle times have passed.
