NOTES:
1.
All voltages are referenced to ground.
2.
I/O pins of fast mode devices must not obstruct the SDA and SCL lines if V
DD
is switched off.
3.

DD
at 5.0V and SDA,SCL = 5.0V, 0°C to 70°C.
5.
See typical accuracy curves for specification limits outside the temperature range indicated.
6.
After this period, the first clock pulse is generated.
7.
The maximum t
HD:DAT
has only to be met if the device does not stretch the LOW period (t
LOW
) of the
SCL signal.
8.
A fast mode device can be used in a standard mode system, but the requirement t
SU: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 t
R
MAX+t
SU:DAT
1000+250 = 1250 ns before the SCL line is released.
9.
C
b
- total capacitance of one bus line in pF.
