Note 1: Not 100% tested. CB = total capacitance of one bus line in pF.
2: As a transmitter, the device must provide an internal minimum delay time to bridge the undened region
(minimum 300 ns) of the falling edge of SCL to avoid unintended generation of START or STOP conditions.
3: The combined TSP and VHYS specications are due to Schmitt trigger inputs which provide noise and spike
suppression. This eliminates the need for a TI specication for standard operation.
4: This parameter is not tested but guaranteed by characterization. For endurance estimates in a specic appli-
cation, please consult the Total Endurance Model which can be obtained on our website.
