I2C SERIAL TIMING SPECIFICATIONS (CONTINUED)
Electrical Specifications: Unless otherwise specified, all limits are specified for T
A = -40 to +125°C, VSS = 0V,
Standard and Fast Mode: VDD = +2.7V to +5.5V
High Speed Mode: VDD = +4.5V to +5.5V.

Conditions
Note 1:
This parameter is ensured by characterization and is not 100% tested.
2:
After a Repeated Start condition or an Acknowledge bit.
3:
If this parameter is too short, it can create an unintentional Start or Stop condition to other devices on the I2C bus line. If
this parameter is too long, the Data Input Setup (TSU:DAT) or Clock Low time (TLOW) can be affected.
Data Input: This parameter must be longer than t
SP.
Data Output: This parameter is characterized, and tested indirectly by testing T
AA parameter.
4:
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 + TFSDA (OR TRSDA).
5:
Time between Start and Stop conditions.
