(Note 4)
Note 1: Not 100% tested. C B = total capacitance of one bus line in pF.
2: 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.
3: The combined T SP and V HYS specifications are due to new Schmitt Trigger inputs, which provide improved noise spike
suppression. This eliminates the need for a T I specification for standard operation.
4: This parameter is not tested but ensured by characterization. For endurance estimates in a specific application, please
consult the Total Endurance? Model which can be obtained from Microchip’s web site at www.microchip.com.
