A fast-mode device can be used in a standard-mode system, but the requirement t
SU:DAT
> 250ns must then be met.
This is automatically 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
RMAX
+ t
SU:DAT
= 1000ns
+250ns = 1250ns before the SCL line is released.
After this period, the first clock pulse is generated.
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.
A device must internally provide a hold time of at least 300ns for the SDA signal (referred to the V
IH MIN
of the SCL sig-
nal) in order to bridge the undefined region of the falling edge of SCL.
