Note 1:
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.
2:
A fast-mode (400 kHz) I2C-bus device can be used in a standard-mode (100 kHz) I2C-bus system, but the
requirement tSU;DAT ≥ 250 ns must then be met. This will automatically be the case if the device does not
stretch the LOW period of the SCL signal. If such a device does stretch the LOW period of the SCL signal,
it must output the next data bit to the SDA line
TR max.+tSU;DAT = 1000 + 250 = 1250 ns (according to the standard-mode I
2C bus specification) before
the SCL line is released.
3:
The MCP46X1/MCP46X2 device must provide a data hold time to bridge the undefined part between VIH
and VIL of the falling edge of the SCL signal. This specification is not a part of the I
2C specification, but
must be tested in order to ensure that the output data will meet the setup and hold specifications for the
receiving device.
4:
Use Cb in pF for the calculations.
5:
Not Tested
6:
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.
7:
Ensured by the TAA 3.4 MHz specification test.
