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

is switched off.

C.
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
≥
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.
8.
C
b
– total capacitance of one bus line in pF.
9.
Internal heating caused by O.S. loading will cause the DS1775 to read approximately 0.5 C higher if
O.S. is sinking the max rated current.
10.
Contact the factory in Dallas, (972) 371-4448, for operation requiring temperature readings greater
than 120°C.
