NOTES:
1. This specification applies over the full operating temperature range.
2. I
PULLUPAC
varies with temperature and V
CC
voltage, as shown in the Typical Performance Characteristics section.
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
B
= total capacitance of one bus line in pF.
6. SDA_IN/SCL_IN = 0.1 V, SDA_OUT/SCL_OUT through resistor to V
CC
.
7. Delays that can occur after ENABLE and/or idle times have passed.
