I2C SERIAL TIMING SPECIFICATIONS (CONTINUED)
Electrical Specifications: Unless otherwise specified, all limits are specified for TA = -40 to +85°C, VDD = +2.7V to +5.0V,
VSS = 0V, CHn+ = CHn- = VREF/2.

Conditions
Note
1:
This parameter is ensured by characterization and not 100% tested.
2:
This specification is not a part of the I2C specification. This specification is equivalent to the Data Hold Time (THD:DAT)
plus SDA Fall (or rise) time: TAA = THD:DAT + TF (OR TR).
3:
If this parameter is too short, it can create an unintended Start or Stop condition to other devices on the bus line. If this
parameter is too long, Clock Low time (TLOW) can be affected.
4:
For Data Input: If this parameter is too long, the Data Input Setup (TSU:DAT) or Clock Low time (TLOW) can be affected.
For Data Output: This parameter is characterized, and tested indirectly by testing TAA parameter.
