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.

, V
SCL
= 5.0V, 0癈 to +70癈.
5. After this period, the first clock pulse is generated.
6. 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.
7. A fast mode device can be used in a standard mode system, but the requirement t
SU:DAT
e 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
R MAX
+t
SU:DAT
= 1000 + 250 = 1250ns before the SCL line is released.
8. C
B
= Total capacitance of one bus line in pF.
9. Internal heating caused by O.S. loading causes the DS1775 to read approximately 0.5篊 higher if O.S.
is sinking the max rated current.
10. Contact the factory for operation requiring temperature readings greater than +120癈.
