NOTES:
1. All voltages are referenced to ground.
2. Internal heating caused by O.S. loading will cause the DS75 to read approximately 0.5癈 higher if
O.S. is sinking the max rated current.

 at 5.0V and SDA, SCL = 5.0V, 0癈 to 70癈.
5. See Timing Diagram in Figure 2. All timing is referenced to 0.9 x V

 and 0.1 x V
