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.
I
CC
specified with T
OUT
pin open.
4.
I
CC
specified with V
CC
at 5.0V and SDA, SCL = 5.0V, 0°C to 70°C.
5.
After this period, the first clock pulse is generated.
6.
A device must internally provide a hold time of at least 300 ns for the SDA signal (referred to the
V
IH MIN
of the SCL signal) in order to bridge the undefined region of the falling edge of SCL.
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
RMAX
+t
SU:DAT
= 1000+250 = 1250 ns before the SCL line is released.
9.
C
b
– total capacitance of one bus line in pF.
10.
Writing to the nonvolatile memory should only take place in the 0
°
C to 70
°
C temperature range.
11.
See typical curve for specification limits outside 0°C to 70°C range. Thermometer error reflects
sensor accuracy as tested during calibration.
