I2C DC and AC parameters
This section summarizes the operating and measurement conditions, and the DC and AC characteristics of the
device in I2C mode. The parameters in the DC and AC characteristic tables that follow are derived from tests
performed under the measurement conditions summarized in the relevant tables. Designers should check that the
operating conditions in their circuit match the measurement conditions when relying on the quoted parameters.
