Note 1:

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:

noise spike suppression. This eliminates the need for a TI 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 at www.microchip.com.
