Note 1:
Not 100% tested. C
As a transmitter, the device must provide an internal minimum delay time to bridge the undefined region
(minimum 300 ns) of the falling edge of SCL to avoid unintended generation of START or STOP conditions.
The combined T
SP
and V
HYS
specifications are due to Schmitt trigger inputs which provide improved noise
spike suppression. This eliminates the need for a TI specification for standard operation.
This parameter is not tested but guaranteed by characterization. For endurance estimates in a specific
application, please consult the Total Endurance Model which can be obtained on our BBS or website.
