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.

5:

Max. clock frequency is 100 kHz for E-temp devices <4.5V. 1.7-2.5V (100 kHz) timings must be used.
