Parameters Sym Min Typ Max Units 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 I
2
C bus line. If
this parameter is too long, the Data Input Setup (T
SU:DAT
) or Clock Low time (T
LOW
) 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 I
2
C specification. This specification is equivalent to the Data Hold Time (T
HD:DAT
)
plus SDA Fall (or rise) time: T
AA
= T
HD:DAT
+ T
FSDA
(OR T
RSDA
).
5: Time between Start and Stop conditions.
