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