Note 1: Not 100% tested.
2: The combined TSP and VHYS specifications are due to new Schmitt Trigger inputs, which provide improved
noise spike suppression. This eliminates the need for a TI specification for standard operation.
3: 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.
4: As a transmitter, the device must provide an internal minimum delay time to bridge the undefined region
(minimum 300ns) of the falling edge of the SCL to avoid unintended generation of start or stop conditions.
