As a transmitter, the device must provide this 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.

it must output the next data bit to the SDA line

The MCP46X1/MCP46X2 device must provide a data hold time to bridge the undefined part between V
and V
must be tested in order to ensure that the output data will meet the setup and hold specifications for the
receiving device.
Use Cb in pF for the calculations.
Not Tested
A Master Transmitter must provide a delay to ensure that difference between SDA and SCL fall times do
not unintentionally create a Start or Stop condition.
