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.
