Conditions

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:

suppression. This eliminates the need for a TI specification for standard operation.

4:

This parameter is not tested but established 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.
