Note 1: All voltages are referenced to ground.
Note 2: Internal heating caused by O.S. loading will cause the DS75LV to read approximately 0.5?/SPAN>C higher if O.S. is sinking the max rated
current.

at 3.0V and SDA, SCL = 3.0V, 0癈 to 70癈.
Note 5: See Timing Diagram in Figure 2. All timing is referenced to 0.9 x V

and 0.1 x V

.
Note 6: After this period, the first clock pulse is generated.
Note 7: For example, if C
B
= 300pF, then t

[min] = t
F
[min] = 50ns.
Note 8: The DS75LV provides an internal hold time of at least 75ns on the SDA signal to bridge the undefined region of SCL's falling edge.
Note 9: This time-out applies only when the DS75LV is holding SDA low. Other devices can hold SDA low indefinitely and the DS75LV will
not reset.
Note
10:
The DS75LV has a maximum operating voltage of 3.7V. Contact Dallas Semiconductor for information on the availability of a 3.7V to
5.5V version of the DS75LV.
